Chris Brown and Frank Ocean along with their entourages reportedly got involved in a brawl at a recording studio in Los Angeles on Monday night (28.01.13).

TMZ first reported that Chris was at Westlake Studio in LA, and when he tried to leave the car park, he was blocked by Frank's car. According to sources, Frank said, "This is my studio, this is my parking spot."

Chris then allegedly tried to shake Frank's hand, and that's when the brawl began.

The New York Post later reported that Chris was the one to throw the first punch.

Chris and his crew had left the scene by the time police arrived. Initially, both sides had not yet pressed charges, although new reports allege that Frank is planning on doing so.

Frank took to Twitter last night after the fight and wrote, "got jumped by chris and a couple guys. lol. i only wish everest was there. (sic)"

"cut my finger now I can't play w two hands at the grammys. (sic)"

This isn't the first feud between the two singers. They were involved in a Twitter war back in 2011 when Chris compared him to songwriters James Fauntleroy and Kevin Cossom. Frank took offence to the comments and hit back by comparing Chris to Sisqo and Ike Turner.

UPDATE: FRANK OCEAN WILL NOT BE PRESSING CHARGES
