Instead of singing, Justin Bieber appears onstage as one of Miley's backing dancers during the 'Party in the U.S.A.' performance.
Miley Cyrus got the party started with a rocking performance on the outdoor stage of 2010 MuchMusic Video Awards. Wearing black shorts and a revealing top, she pumped up the crowd with a "Party in the U.S.A." performance.
The "Hannah Montana" actress who also co-hosts this June 20 event was backed by a number of dancers during the set. Moreover, she got Justin Bieber halfway through the performance. The Canadian pop star hopped on a bike, making the girls scream even louder.
Other performances of the evening came from the likes of Katy Perry, Ke$ha and Adam Lambert. Katy sang "California Gurls", Ke$ha delivered "Tik Tok" and Adam entertained fans with "Whataya Want From Me". Additionally, Justin also appeared on stage for another performance in addition to supporting Miley's kick-off show.
