Early and personal life
[edit]Born on Long Island, New York, Castro was raised in both New York and Georgia. At age 17, he was shunned by his parents (both Jehovah's Witnesses) for being gay, leading him to finance his education independently in the Savannah College of Art and Design.[3]
Sebastian Castro came out as gay on a Philippine podcast Beki Nights shortly after releasing his viral music video. When asked why he chose to come out on the GMA Network show H.O.T. TV, he responded, "I know there are lots of people out there that are scared to be themselves."[4]
In 2014, Sebastian Castro and former ABS-CBN Reporter Ryan Chua publicly acknowledged their relationship over social media.[5] Castro made the announcement during a trip to London where Ryan was undergoing a masters program at City University of London.[6] After a public four-year relationship, the two separated in September 2017.[7]
In April of the following year, several showbiz outlets romantically linked Castro to actor and television host Paolo Ballesteros after photos of them together surfaced. Neither ever publicly commented on the rumors. In June, Castro acknowledged he had a relationship that ended, but never identified the other party.[8][9][10][11]
Career
[edit]On February 14, 2013, Castro's first music video "Bubble" appeared on YouTube, quickly garnering over 3 million views. Bubble further popularized the dance crazy "Bubble Pop," particularly in the Philippines.[12][13] The music video was Sebastian Castro's "coming out." Prior to releasing the homo-erotic Bubble music video, Castro was not publicly open about his sexuality.[2][3]
Castro has landed several major product endorsements in SouthEast Asia, including Jollibee, Pantene Hair, and Sun Cellular.[2][14] He was featured among the Philippine Cosmopolitan Bachelors of 2012 and is currently an endorser of Fujifilm, Durex, Cathy Valencia, and Blued.[2][15][16][17]
After being cast in several minor and supporting roles on TV and Film over the course of five years, Sebastian Castro appeared in his first lead role in full feature film 4 Days (2017), an independent film by Filipino director Adolfo Alix Jr.[18][19]
PLM Film Society heralded the film as "one of the more inventive films of the genre in recent memory," adding "Mikoy Morales and Sebastian Castro complement each other onscreen, Morales with his tough and heartbreaking take on Mark, and Castro filling Derek full of reservations, doubts and an unspoken multitude of feelings."[20]

View on GrokipediaEarly life
Upbringing and family background
Sebastian Castro, born Benjamin Brian Castro on December 22, 1989, in Long Island, New York, was raised in both New York and Georgia by parents of Peruvian and Japanese descent.[3][8] His family adhered to Jehovah's Witnesses beliefs, which profoundly shaped his early environment.[3] At age 17, Castro was disowned by his parents upon their discovery of his homosexuality, severing familial ties and compelling him to achieve financial independence at a young age.[8][3] This rupture motivated him to self-finance his subsequent education, marking a pivotal shift toward self-reliance in his upbringing.[8]Education and early influences
Castro, born to parents of Peruvian and Japanese descent, faced significant personal challenges in his youth that shaped his path toward independence and creative expression. At age 17, he was disowned by his Jehovah's Witness parents after revealing his homosexuality, an event that severed familial financial support and compelled him to support himself.[9] [3] This rupture fostered a drive for self-reliance, influencing his later emphasis on authenticity and resilience in artistic endeavors, as he has publicly reflected in personal accounts of navigating isolation and rebuilding connections.[10] To pursue higher education, Castro enrolled at the Savannah College of Art and Design (SCAD) in Georgia, self-financing his studies through various means amid his circumstances.[8] At SCAD, he focused on arts programs that honed skills in visual and performing arts, providing foundational training relevant to his emerging interests in modeling, acting, and content creation. However, he withdrew from the institution in early 2014, shortly after securing his first major acting role in the Philippines, prioritizing professional opportunities over completing his degree.[8] This transition marked a pivotal shift, channeling early adversities into a career trajectory centered on self-expression through media.Personal life
Relationships and family
Castro was raised by parents who are adherents of Jehovah's Witnesses. At age 17, following his coming out as gay, he was shunned by his family in accordance with the religion's practices toward those who diverge from its doctrines on sexuality.[9] This estrangement persisted for over a decade until the COVID-19 pandemic prompted a reconciliation, with Castro reporting in October 2022 that he had reestablished contact with both parents for the first time since his teenage years.[9] Castro publicly came out as gay in a February 2013 YouTube video during a live stream on the Philippine show Becky Nights, marking a pivotal moment in his openness about his sexuality.[11] He has since expressed a preference for romantic partners who are also openly gay, citing his own prolonged experience of being closeted until age 23 as a factor in avoiding relationships with those still in the closet.[12] In his romantic history, Castro was in a four-year relationship with former TV Patrol reporter Ryan Chua, which ended in 2017; he attributed the breakup to differing life priorities and personal growth. He began dating Silang, Cavite Vice Mayor Aidel Paul Belamide in late 2018, publicly confirming the relationship in June 2019 during Pride Month, after keeping it private initially due to Belamide's public role.[13] No public updates on this or subsequent relationships have been reported as of 2023.[14]Lifestyle and public persona
Castro projects a candid and relatable public persona, characterized by openness about his personal experiences, including his sexuality and family estrangement. He publicly came out as gay in 2013 via a YouTube video, which contributed to his rise as an internet personality with a significant following in Southeast Asia.[15] His content often blends humor, vulnerability, and cultural commentary, resonating with audiences through authentic storytelling rather than polished celebrity image.[16] In terms of lifestyle, Castro favors a casual, unpretentious approach to daily attire, often opting for simple outfits like basketball shorts and tank tops over fashion-forward ensembles, reflecting a preference for comfort amid his modeling and acting career.[17] He has expressed a commitment to dating only partners who are openly gay, drawing from his own experiences of remaining closeted until age 23 and the challenges of concealment.[12] By 2022, he reconciled with his parents after years of estrangement stemming from his coming out at 17, marking a personal milestone amid ongoing professional pursuits.[9] Castro's lifestyle incorporates frequent international travel, particularly between the United States and the Philippines, as documented in his YouTube vlogs featuring trips to Cebu and Manila, which highlight his cultural ties and leisure activities.[18] More recently, he has ventured into real estate in North Atlanta, Georgia, listing properties and sharing professional updates on social media, indicating a diversification beyond entertainment.[19] This blend of creative endeavors, personal advocacy, and entrepreneurial activities underscores a dynamic, self-reliant public image.Career beginnings
Entry into entertainment industry
Sebastian Castro entered the entertainment industry in early 2011, shortly after arriving in the Philippines on January 6 for what was initially planned as a brief two-to-three-week visit. While there, he was scouted on his second day and cast in a television commercial for Sun Cellular, marking his professional debut in commercial modeling.[17][20] At age 21 and previously based in Los Angeles, Castro opted to extend his stay to capitalize on the opportunity, transitioning from personal pursuits in the United States to paid work in the Philippine advertising sector.[17] This scouting occurred while Castro was dining out, highlighting the serendipitous nature of his discovery amid a burgeoning career in modeling and on-camera appearances.[17] The Sun Cellular campaign provided his first verifiable exposure in a commercial context, establishing him as a Peruvian-Japanese American talent appealing to Southeast Asian markets.[15] Subsequent opportunities in Philippine commercials followed, solidifying his foothold before expanding into acting and music.[20]Initial acting and modeling work
Castro began his professional entertainment career in the Philippines with modeling work shortly after arriving in Manila on January 6, 2011.[17] He booked print advertisements, billboards, and television commercials, establishing himself as a commercial model.[21] Among his early campaigns were television and print ads for Pantene, featuring co-star Angelica Panganiban; Jollibee; and Sun Mobile.[15] These assignments involved on-camera performances, serving as his introductory experience in promotional acting while emphasizing visual appeal typical of modeling.[22] By 2014, Castro had gained recognition in Philippine media, including a feature as a "Cosmo hunk" in Cosmopolitan Philippines, which showcased his physique and charisma in fashion spreads.[17] This exposure built on his commercial foundation, positioning him for scripted roles. His transition to narrative acting followed, with initial appearances in supporting capacities on the long-running anthology series Maalaala Mo Kaya, credited from the mid-2010s onward.[7] These episodes provided early opportunities to develop dramatic skills beyond advertisement spots, though specific debut dates remain undocumented in public records.[23]Acting career
Breakthrough roles in film
Castro achieved his breakthrough in film with the lead role of Derek Hernandez in the 2016 drama 4 Days, directed by Adolfo Alix Jr.[24][25] The film, an entry in the Cinemalaya Independent Film Festival, depicts the evolving relationship between two friends grappling with personal demons and unspoken affections, marking Castro's first starring role in a full-length feature after years of supporting parts.[26][27] Co-starring Mikoy Morales as Mark, 4 Days premiered on August 5, 2016, and highlighted Castro's ability to portray complex emotional dynamics, earning praise for the onscreen chemistry between the leads.[25][24] Prior to 4 Days, Castro gained international exposure through his role in the 2013 anthology Voyage, directed by Scud (Danny Cheng Wan-Cheung), where he starred as Sebastian in the "Fall in Love" segment.[2][28] This Hong Kong production, which premiered at the Hong Kong International Film Festival on April 7, 2013, explores themes of love, loss, and existential voyages across multiple stories, positioning Castro as a top-billed actor in an artistic, boundary-pushing narrative known for its explicit content and introspective style.[28][29] The role showcased his versatility in independent cinema, bridging his early career from television to more experimental film work.[8] In 2017, Castro portrayed Atty. Victor Cruz, a gay law professor, in the ensemble film Bar Boys, directed by Kip Oebanda.[30][31] The movie, released on August 16, 2017, follows five friends navigating law school challenges and personal growth, with Castro's character providing mentorship and adding depth through his nuanced depiction of identity and relationships.[30][32] This supporting role further solidified his presence in Philippine cinema, demonstrating range beyond lead romantic parts.[32]Notable collaborations and projects
In the 2016 independent film 4 Days, directed by Adolfo Alix Jr., Castro starred as Derek Hernandez alongside Mikoy Morales, portraying two friends whose platonic bond deepens into romance amid personal hardships.[24] The project marked one of Castro's early leading roles, emphasizing themes of emotional intimacy and recovery from relational trauma, with the actors drawing from their own experiences to inform their performances.[24] Castro played Atty. Victor Cruz, a gay law professor, in the 2017 ensemble comedy-drama Bar Boys, collaborating with principal actors Carlo Aquino, Rocco Nacino, Enzo Pineda, and Kean Cipriano, who depicted aspiring law students navigating academic and personal challenges.[32] His character's mentorship and subplot interactions, including key scenes with Aquino's role, highlighted mentorship dynamics and identity struggles within the film's broader examination of friendship and ambition.[32] In 2023, Castro led the seven-episode boys' love series Stay, co-starring with Korean-American actor Ellis Gage as a Filipino filmmaker relocating to Los Angeles for opportunities, where their characters develop a romantic connection across cultural lines.[20][33] Produced by Team Campy Entertainment and filmed in California, the series blended Filipino-American perspectives on migration, identity, and queer relationships, with Gage noting the on-set chemistry fostered authentic emotional depth.[33]Music career
Debut releases and singles
Castro's entry into music coincided with the premiere of his debut single "Bubble" via a music video uploaded to YouTube at midnight on February 14, 2013.[16] The track, characterized as dance-pop, was officially released as a digital single on July 3, 2013.[34][35] On November 16, 2013, Castro issued his debut album S.E.B., a nine-track project self-released and featuring explicit content in its dance-pop style.[36][37] Key tracks included "02.19.2013" (3:02), "S.E.B." (3:20), "You're Gay" (3:09), "Baboy" (3:04), "You Will Die" (3:38), "Theban" (3:21), "Fart" (3:05), "Bubble 2.0" (an updated version of the lead single, 3:48), and "Show Me Yours" (3:25).[38] Additional singles from this period encompassed "Bears," released in 2013, which aligned with the album's thematic irreverence.[39] These early outputs marked Castro's transition from acting and modeling to music, leveraging his online presence for initial distribution and visibility.[40]Style and thematic elements
Castro's music primarily adheres to pop conventions, featuring upbeat rhythms, synthesized production, and accessible melodies designed for viral appeal on platforms like YouTube. His debut single "Bubble," released on February 14, 2013, exemplifies this approach with its dance-oriented structure and electronic flourishes, later expanded through remixes such as the "Toy Armada's Cherry Poppin' Dub."[41][42] The 2013 album S.E.B., comprising nine tracks, maintains this pop framework, blending vocal-driven hooks with light electronic elements to prioritize catchiness over complexity.[43] Thematic content in Castro's releases centers on explicit explorations of gay male desire and identity, presented through direct, unfiltered lyrics that challenge taboos around homosexuality. In "Bubble," the narrative revolves around infatuation with a man's physique, employing vivid imagery such as references to "bubble" (buttocks), "stubble," and "muscles" to convey physical lust in a celebratory tone.[44] This extends to tracks like "You're Gay," which playfully confronts sexual orientation with repetitive assertions like "You're gay, you just don't know it yet," framing denial or discovery as a lighthearted revelation.[45] Such themes reflect Castro's openly gay persona, leveraging provocation and humor to assert visibility, particularly resonating in Southeast Asian markets where the "Bubble" video amassed millions of views shortly after launch.[16] His work avoids subtlety, opting for raw candor that aligns with internet-era shock value rather than introspective depth, as seen in the absence of broader social commentary beyond personal sexuality.[40]Online presence and YouTube
Rise as a content creator
Sebastian Castro launched his YouTube channel on December 21, 2011, initially sharing personal vlogs and milestone videos, including a public coming-out announcement that contributed to his early visibility among LGBTQ+ audiences.[46] His content focused on everyday experiences, humor, and self-expression, which resonated particularly with viewers in the Philippines and broader Southeast Asia, where he developed a dedicated fanbase through relatable storytelling and unfiltered discussions on identity and relationships.[47] Castro's breakthrough as a content creator accelerated in 2013–2014 with the release of his music video "Bubble," which debuted on YouTube on February 14, 2013, and quickly trended due to its catchy pop style and themes of unrequited love, amassing significant views and shares in the region.[16] This video, alongside live performances and covers, showcased his vocal talents and marked a shift toward multimedia content blending acting clips, music, and vlogs, helping him transition from niche online personality to recognized YouTube sensation by mid-2014.[48] Interviews from that period highlighted his growing influence, with outlets noting his appeal as a "Cosmo hunk" and rising digital star amid a burgeoning Philippine vlogging scene.[17] By 2014, Castro's channel had cultivated a loyal following through consistent uploads of challenges, Q&A sessions, and social commentary, often featuring collaborations with local influencers and appearances in Philippine media like Pantene campaigns that amplified his online reach.[49] This period solidified his status as an internet celebrity, with content emphasizing authenticity over polished production, driving organic growth via word-of-mouth in Southeast Asian communities where English-language personal narratives were scarce. His strategic engagement—responding to comments and incorporating viewer suggestions—fostered community loyalty, setting the stage for crossovers into acting and music projects.[17]Key videos and audience engagement
One of Sebastian Castro's breakthrough YouTube videos was "Bubble (Official)", uploaded on February 12, 2013, which amassed over 3.8 million views and trended shortly after its Valentine's Day debut, contributing to his early viral appeal in Southeast Asia.[41][16] The track's playful, pop-infused style and music video format helped establish his online persona as a multifaceted entertainer blending music and visual content. Similarly, "Theban (Official)", released around the same period, garnered approximately 4.9 million views, solidifying his music video output as a cornerstone of his channel's content.[50] These videos featured explicit themes and censored variants, with the latter version uploaded on November 22, 2013, receiving 555,000 views, reflecting audience interest in edgier material.[51] Castro's channel, which maintains 158,000 subscribers and over 16.5 million total video views as of recent metrics, demonstrates sustained engagement through a mix of music releases, personal vlogs, and later real estate content.[46] High-view legacy videos like "Bubble" and "Theban" contrast with more recent uploads, such as "I'm Back Home (First Time In 3 Years)" from 2023 with 42,000 views, indicating a shift in focus but retained core audience loyalty. Engagement patterns show millions of cumulative interactions on early music content, driving his status as an internet celebrity particularly in regions like the Philippines and Singapore, where cross-promotion via TV guestings amplified reach.[18]Reception and legacy
Critical and commercial assessment
Castro's music releases, particularly the viral singles "Bubble" (2013) and "Theban" (2013), achieved substantial online viewership, accumulating over 3.8 million and 4.9 million views on YouTube, respectively, primarily appealing to LGBTQ+ audiences through explicit themes of gay identity and historical queer representation.[41][52] However, broader commercial metrics indicate limited mainstream penetration, with Castro's Spotify profile reporting only 565 monthly listeners as of recent data, suggesting sustained interest confined to niche digital platforms rather than widespread streaming or sales success.[53] In acting, Castro's roles in independent films such as 4 Days (2016), where he portrayed a character navigating unspoken romantic tension with a friend, earned modest critical notice focused on themes of self-discovery and unrequited affection, but the film holds an average IMDb rating of 5.2/10 from 117 user reviews, reflecting divided responses to its pacing and emotional depth.[25] His appearance in the 2023 boys' love series STAY, centered on a Filipino filmmaker's experiences in Los Angeles, positioned him within emerging Southeast Asian queer media, yet formal reviews remain sparse, with audience discussions emphasizing representational value over artistic innovation.[54] Overall, Castro's reception underscores a pattern of digital virality driving initial fame—fueled by provocative, identity-affirming content—without translating into enduring commercial viability or critical acclaim in traditional outlets, as evidenced by the absence of major awards, box office data, or peer-reviewed analyses in film and music journalism. This niche trajectory aligns with his self-described pivot toward online content creation, where engagement metrics like YouTube subscribers (158,000) outpace conventional industry benchmarks.[18]Public controversies and criticisms
In October 2013, rumors spread via social media and messaging platforms in the Philippines alleging the existence of a sex tape featuring Castro and actor Enchong Dee, prompting public speculation during Dee's vacation abroad.[55] Both individuals denied the claims, with Dee dismissing the rumor as a potential hoax or publicity stunt and expressing ironic curiosity about its content as an indicator of his fame.[56] No video ever surfaced, and the incident highlighted early scrutiny of Castro's rising visibility following his "Bubble" video release earlier that year.[57] Castro's 2017 breakup with journalist Ryan Chua after a four-year relationship drew media attention, with Castro publicly attributing the split to personal differences in an exclusive interview.[58] The disclosure fueled discussions in Philippine entertainment circles, though it did not escalate into broader scandal.[59] His explicit LGBTQ+-themed content, such as the 2013 "Bubble" video, elicited mixed reactions in the socially conservative Philippine context, including general online bashing tied to his openness about sexuality, but no organized backlash or professional repercussions were documented.[56] Castro has otherwise maintained a low profile on controversies, with limited verifiable criticisms of his artistic or personal conduct emerging in subsequent years.Filmography

Discography
Singles
Castro's initial foray into music singles came with "Bubble", released in 2013, a comedic track that garnered millions of views on YouTube due to its explicit, humorous lyrics and video content centered on personal hygiene themes.[53][50] The single was later included in his album of the same name, but its standalone release marked his breakthrough in online music virality, amassing over 3.8 million YouTube views by 2025. Subsequent tracks from the 2013 album S.E.B., such as "Theban" and "Fart", received individual music video releases and streaming promotion, functioning effectively as singles despite being album cuts; "Theban" alone exceeded 4.9 million YouTube views.[37][50] In 2021, Castro released "Free as a Bird" (featuring Knave of Songs) as Seb Castro, an explicit single available on platforms like Spotify and Amazon Music, representing a shift toward more straightforward rock influences compared to his earlier pop-parody style.[68][69] No additional standalone singles have been documented through major streaming services as of October 2025, though Castro's music output remains tied to YouTube-driven popularity rather than traditional chart success.[40]| Title | Release Year | Notes |
