Sometimes celebrities lose their tempers (some more than others), and last night (January 27) Chris Brown and Frank Ocean were involved in a bit of a tussle.

According to a report it all went down at Westlake Studio in Los Angeles, where both recording artists happened to be working on different projects.

Chris supposedly tried to shake Frank’s hand after Ocean’s entourage blocked Brown’s exit from the building. However, Frank’s entourage saw the move as an act of aggression and attacked the crew.

However, another source says Brown started complaining about a parking space and it escalated until it “allegedly led to Chris Brown punching the victim.”

After police showed up and broke it up, Ocean tweeted, “got jumped by chris and a couple guys. Lol… cut my finger now I can’t play w two hands at the grammys.”

Given Brown’s propensity for violence, it wouldn’t be surprising if he gets into trouble for the incident. Stay linked to the GossipCenter for all the latest on this developing story.
