Justin Bieber might be the latest young artist to have taken the music scene by storm, but the pint-sized pop-star's rise to fame isn't the most conventional. The 16-year-old Canadian first caught the radar as a YouTube star, when his mother uploaded shaky home-recordings of his performances at local events.
The amateur footage caught the attention of Atlanta manager Scooter Braun who then introduced Bieber to RnB superstar Usher. The rest is history. Now the star's baby-faced looks and high-pitched voice have garnered a massive following and his debut album 'My World' hit platinum soon after its release in November 2009.
Here are his most notable YouTube appearances:
