The 16-year old was named Best New Artist and proceeded to show why with a medley of three classic songs.
Introduced outside of L.A.'s Nokia Theatre by Kim Kardashian, Bieber was full of energy as he bounded on stage, fell into the arms of (lucky!!!) backup dancers and showed off his drum-playing skills.
It was all part of a medley that included snippets of "U Smile," "Baby" and "Somebody to Love." But don't just read about this artist's fun antics. Watch them for yourself in the video below!
