Justin Bieber was first discovered in 2008 after his YouTube videos were seen by American talent manager Scooter Braun, who introduced the teen to Usher and secured him a record deal.
The Canadian teen's 2009 debut, My World, was certified platinum in the USA, and saw him become the first artist to have seven tracks from a debut album chart in the Billboard Hot 100. With tracks like One Less Lonely Girl and Love Me, Justin began winning the hearts of girls around the world.
Bieber Fever proved just as infectious with his first full studio album, My Worlds, which spawned his mega-hit single Baby. The video for the track broke online records and became one of the most viewed and discussed ever on YouTube.
