Adam Lambert, Katy Perry, Justin Bieber Perform At 2010 MuchMusic Video Awards

Miley Cyrus swept into the MuchMusic Video Awards last night and claimed International Video Of The Year for “Party In The U.S.A.” (and her performance of the song even featured a cameo by the night’s multiple winner Justin Bieber). But it was Adam Lambert’s half-buzzed-off head of hair that got the kids squealing. Glambo nabbed the Fave International Video MMVA for “Whataya Want From Me” and performed the hit single on the outdoor stage. Head below to also see performances by Ke$ha, Justin Bieber, Drake and Katy Perry at what is essentially Canada’s version of the VMAs.
