The Biebs took home the win for "U Smile," winning out over Em's "Love the Way You Lie," Cee Lo Green's "F--- You," Bruno Mars' "Grenade" and Kanye West's "All of the Lights."
After presenter Kim Kardashian announced his name, Bieber popped up, snagged a smooch with girlfriend Selena Gomez, and headed up onstage, where he delivered a heartfelt message about the role of a higher power in his ascendance to the top of the young pop crop.
"I just want to say thank you so much, not only to God but to Jesus," Bieber said. "Because I wouldn't be here without Him. He's really blessed me. He's put me in this position. So I want to say thank you so much."
The win marked two Moonmen in two years for Bieber, who nabbed Best New Artist for "Baby" at the 2010 VMAs (besting Ke$ha, Nicki Minaj and Jason Derülo) and who is quickly making certain his name and music are deeply engrained in the MTV award show. Last year, of course, Bieber opened the VMAs with a medley outside in Nokia Plaza. This time around, he skipped a performance but still found himself at the center of the action inside the theater.
"Also, I want to say thank you to all the other nominees," Bieber said. "They were amazing. I'm a true fan of all of them, so I want to share this award with all them. You guys are amazing."
