Chris Brown "quickly called his lawyer" after he was involved in a fight.

The R&B singer and rapper Drake are said to have clashed in New York City nightclub WIP in the early hours of Thursday morning.

Chris' attorney Mark Geragos was there for his client immediately following the altercation.

"Chris quickly called his lawyer in the minutes after the attack," a source told Radar Online. "Contrary to reports Chris didn't flee from the scene, it was a very fluid situation and Chris just wanted to make sure that his girlfriend, Karreuche Tran, was safe. Luckily for Chris, his attorney happened to already be in New York City and he has been talking with detectives from the NYPD and with management at the nightclub. Chris, Karreuche and other members of his entourage will fully cooperate with law enforcement."

Chris is still on felony probation for assaulting Rihanna at the Grammys years ago.

It is thought that he doesn't want to get into anymore legal trouble.

"Chris will do whatever is asked of him and will be formally questioned about the club melee," the source continued.

Authorities are actively investigating the incident and video footage of the fight taken by partygoers is surfacing.
