Justin Bieber Teams with Mariah Carey, French Montana & T.I.

Justin Bieber has teamed with Mariah Carey, French Montana and T.I. for a new song. “Why You Mad” the Infinity remix is the title of their newest track.

Justin’s collaboration with Mariah and co. came about a bit randomly. He was at the studio working on his own music when he discovered Mariah was in a neighboring studio with French Montana.

After spending some time talking, Justin decided to hop in the booth and record a few vocals for the track. What do you think?
