Bieber, seen on April 24, 2010, in Sydney, Australia, first came to fame when his mother uploaded videos to YouTube of him singing. A musical marketing executive clicked on one of them -- reportedly by accident -- and the teen was eventually signed to the record label of R&B star Usher. Born in 1994 to a teenage mom who raised him alone while working low-paying jobs, the singer has come a long way. His first full studio release, "My World 2.0," debuted at No. 1 on Billboard's Hot 100 chart. Brendon Thorne / Getty Images

Bieber performed during the Easter Egg Roll on the South Lawn of the White House in Washington on April 5, 2010. He has performed at the White House twice.
