Most exciting performance
Justin Bieber established his performance cred (kind of) by performing a stripped-down version of 'As Long As You Love Me,' although I still don't think anyone should wear a baseball cap backwards, as he did. But then the Biebs rocked (popped?) the house with his 'Beauty and a Beat' guest Nicki Minaj. We're not quite sure if Minaj (this time decked out in black) actually used the word 'Selener' in her performance (referencing Bieber's ex Selena Gomez) but it sounded like it. Kudos, if so, for maintaining the integrity of the song.
