Sunday night's MuchMusic Awards were co-hosted by Selena Gomez, but the big winner of the night was her boyfriend, Justin Bieber.

Bieber was voted favorite artist by Canadians for his "Somebody to Love" video, and the video shared the best international video award with Drake for his "Find Your Love" vid.

When Justin came on stage to accept his first award of the night, he said, "Selena? Nice to meet you, I'm Justin. You're very beautiful. Maybe we could go out sometime?"

TOO cute!

Lady Gaga also took home some major accolades -- she was voted most popular international artist and took home awards for "Judas." She performed twice at the show, which is held in Toronto. Gaga opened the show with "The Edge of Glory" and closed out the night with "Born This Way."
