Diamonté Quiava Valentin Harper (born July 2, 1993), known professionally as Saweetie (/səˈwiːti/; also pronounced as simply "sweetie"), is an American rapper, singer and actress. Her 2017 debut single, "Icy Grl", received double platinum certification by the Recording Industry Association of America (RIAA) and led her to sign with Warner Records in a joint venture with her then-manager Max Gousse's record label, Artistry Worldwide.

Her debut extended play (EP), High Maintenance (2018) was met with lukewarm reception and failed to chart. Her second, Icy (2019) moderately entered the Billboard 200 and spawned the single "My Type", which marked her first entry—at number 21—on the Billboard Hot 100 and received quadruple platinum certification by the RIAA. Her 2020 single, "Tap In" and her 2021 single, "Best Friend" (featuring Doja Cat), both peaked within the chart's top 20, and are preceding the release of her forthcoming debut studio album, Pretty Bitch Music. At the 64th Annual Grammy Awards, the latter song earned a nomination for Best Rap/Sung Performance, while Harper herself was nominated for Best New Artist.

Diamonté Quiava Valentin Harper was born on July 2, 1993, in Santa Clara, California, to former video vixen Trinidad Valentin, who is of Filipina and Chinese descent, and Johnny Harper, who is African American. She grew up in Hayward and later in Sacramento, attending Merrill F. West High School in Tracy and graduating from Monterey Trail High School in Elk Grove. She began writing music at age 13. After high school, she attended San Diego State University, where she studied communication and business before transferring to the University of Southern California, where she completed her degree and received a Bachelor of Arts (BA) in Communication. After graduating in 2016, she began to focus on her rap career.

Saweetie began posting clips of her freestyles to her Instagram account in 2016. One video featured her rapping over the beat from fellow female rapper Khia's "My Neck, My Back (Lick It)", which eventually became "Icy Grl". The song was released on her SoundCloud in the summer of 2017 and brought her to the attention of Max Gousse, a well-known producer and A&R executive, who became her manager. The video went viral online, accruing 100 million views on YouTube as of June 2020.

That same month, Saweetie released a freestyle rap, "High Maintenance", accompanied by a short clip of herself rapping a verse to the song, which also went viral on Instagram and Twitter. In October 2017, she released a video for her song "Focus", which samples DRAM's "Gilligan".

In January 2018, Saweetie was named Tidal's Artist of the Week and one of Pigeons & Planes's Best New Artists of the Month. During Super Bowl LII in February 2018, she was featured in an ad for Rihanna's cosmetic company, Fenty Beauty. That month, she signed to Warner Bros. Records (since May 2019 Warner Records) and Gousse's record label, Artistry Worldwide.

I do a lot of covers but this is the first time I'm actually doing original content. I leave the studio and I come home wanting to listen to really myself.
