Chris Brown has been in the studio non-stop since being released from jail but did he still manage to get into some trouble..?

Sources tell All Hip Hop that Chris Brown and Justin Bieber’s respective crews got into a fist-fight while the two embattled pop stars worked on a track together at the Record Plant in Hollywood.

Coincidentally, that same night paparazzi website X-17 reported seeing Justin Bieber storm out of the studio. In other Chris Brown news after his release from jail his official girlfriend Karrueche Tran hosted a party for him that went sour. A few days after the party Karrueche Tran cryptically Tweeted “You can’t trust no f**kin body. What a damn shame.

Chris Brown was spotted later that week at the Maxim Hot 100 party without Karrueche and surrounded by hordes adoring women.
