Justin Bieber's 'Boyfriend' Sessions 'Definitely Insane'

Ahead of Thursday's video premiere on MTV, Mike Posner says Justin 'can go from zero to insane in a matter of five minutes.'

Justin Bieber's "Boyfriend" video is ready to drop this Thursday. The teen pop superstar will sit down with MTV News during the latest installment of "MTV First" to premiere the clip.

But, long before he hit the Los Angeles-area set for the video, Bieber hit the studio with Mike Posner and Mason Levy to work on the track.

Leading up to Thursday's video premiere, MTV News got the scoop from Posner himself about recording the first Believe single. "Justin's super hands-on with his music," he explained. "He comes up with amazing melodies — that's what I was most impressed by. We'd put on a beat or something, and he goes into a booth, and he freestyles these melodies, and they're crazy."

What was equally crazy was the way Bieber's fans would find out when and where the guys were working on the cut. "With Justin, we kept the studio pretty locked down just because he can go from zero to insane in a matter of five minutes," Posner recalled of the studio sessions. "It was definitely insane. I was just honored to be a part of the project."

The track is a tease to the June 19 album release. And, Posner shared that Bieber wants to change the rules of the pop game. "He gets it," he said. "He wants to make something that other people aren't doing right now, and that's what we've achieved."
