It may not be his all-time favorite but Justin Bieber is obsessing on Carly Rae Jepson’s “Call Me Maybe.” The Biebs announced via TwitVid last week that he’d signed Jepson to his new label and this week brings a homemade YouTube video of Justin, Selena Gomez, Ashley Tisdale, Big Time Rush’s Carlos Pena, and a few of their friends to the track.

Check it out after the jump. Justin busts a move, Selena sings into a banana, and Ashley Tisdale interrupts an almost-kiss.
