Justin Drew Bieber was born to 18-year-old Pattie Mallette and 19-year-old Jeremy Bieber in London, Ontario, Canada. His parents never married and split up when he was a toddler.

At the age of 13, Justin Bieber was discovered by American record executive Scooter Braun after Braun accidentally clicked on one of Bieber's YouTube videos covering Ne-Yo's 'So Sick.' Braun was impressed and contacted Bieber's mother, leading to Bieber recording demo tapes in Atlanta, Georgia, and eventually signing with Raymond Braun Media Group (RBMG) and Island Records.

Bieber released his debut EP, 'My World,' which quickly gained international commercial success and established him as a teen idol. This marked the beginning of his mainstream career.

Bieber's debut studio album, 'My World 2.0,' debuted atop the US Billboard 200 chart, making him the youngest solo male act to achieve this in 47 years. The album was supported by the hit single 'Baby' featuring Ludacris, which became one of the best-selling singles of all time.

Bieber released his fourth studio album, 'Purpose,' which marked a significant shift towards R&B and EDM sounds. The album debuted at number one on the Billboard 200 chart and included collaborations with artists like Big Sean, Halsey, and Travis Scott. It also produced three Billboard Hot 100 number-one singles: 'Love Yourself,' 'Sorry,' and 'What Do You Mean?'

Following the release of 'Purpose,' Bieber embarked on the Purpose World Tour, which started in Seattle, Washington, on March 9, 2016. This tour was a global success and further solidified his status as a pop icon.

Bieber made UK chart history by becoming the first artist to occupy the entire top three of the UK Singles Chart with 'Love Yourself,' 'Sorry,' and 'What Do You Mean?' He also featured on the singles 'I'm the One' by DJ Khaled and 'Despacito' by Luis Fonsi, both of which peaked at number one on the Billboard Hot 100.

Bieber released his R&B-inspired fifth album, 'Changes,' which debuted at number one in both the UK and US. The album was supported by the standalone duet single 'Stuck with U' with Ariana Grande, which also debuted atop the Billboard Hot 100.

Bieber released his sixth album, 'Justice,' which was supported by the worldwide hit single 'Peaches.' The album topped the Billboard 200, breaking Elvis Presley's 1965 record for the youngest solo act to have eight US number-one albums.

Bieber's eighth US number-one single, 'Stay' with The Kid Laroi, was released in 2021. This further cemented his position as one of the most successful artists in contemporary music.
