Chris Brown and Justin Bieber Reunite For New Music

Chris Brown and Justin Bieber are back in the studio working on new music together.

The troubled pair broke the news via Instagram this week, sharing pictures from their time together, including a shot with Akon.

"Studio, me and CB did 1 for the fans," Justin Bieber shared with one of the pictures.

It's unclear what direction the two have taken for this collaboration, but it follows their 2011 track "Next 2 You," which appeared on Chris Brown's album "F.A.M.E."
