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.
