Collabo alert! Pals Justin Bieber and Adam Levine, who have been known to meet up on the court and shoot some hoops together, hit the studio on Monday (March 12). The Biebs is hard at work on his new album 'Believe,' and he's called upon Timbaland and Usher to help with the mission. Now, 'The Voice' coach Levine is on board and getting his hands dirty with the teen idol.

The Biebs tweeted from the studio, teasing that there is a "big idea" on the horizon and used the "#supergroup" hashtag, which could mean that others are involved. OMG, what could it be? No fair that he's teasing us. We need more info or we're going to burst.

Scooter Braun, who manages the teen, also tweeted about the studio fireworks these two were creating, posting: "i think they were battling at TEMPLE RUN," referring to the handheld game. He also shared the photo of the dynamic, hat-wearing duo.
