Hollywood invaded Toronto, Canada, on Sunday night as the stars gathered for the 2010 MuchMusic Video Awards.
Miley Cyrus joined Justin Bieber, Katy Perry and Adam Lambert up North for the celebration.
Justin was the star in his home country, nabbing three awards — UR FAVE Video, UR FAVE New Artist and International Video by a Canadian.
The Bieb later tweeted, "2nite is 1 of those nights i will never forget. Thank u to every fan who ever cared or supported or listened to a song. U did this. Thank u!"
