Chris Brown and Drake fight over Rihanna at nightclub

I just learned that rapper Drake and his entourage got into a FIGHT . . . with CHRIS BROWN at the popular AFTER HOURS NYC nightclub WIP.

According to MULTIPLE MediaTakeOut.com snitches inside, Chris and Drake have had a DIFFICULT relationship since three years ago - when Rihanna CHEATED on Chris, with Drake. Chris has HELD A GRUDGE against Drake for years.

Well last night at WIP, we're told that Chris reportedly sent over a bottle of champagne to Drake's table, as a sort of peace offering. We're not sure WHAT happened next, but we're hearing UNCONFIRMED REPORTS that Drake sent the bottle back to Chris with a message to the effect of - "I'm f**kng the love of your life [Rihanna], deal with it.

Chris Brown is said to have been angered by the message and immediately went over to where Drake and his crew were sitting to confront him.

Meek Mill, another rapper who has had a fling with Rihanna was also present.

Mediatakeout reports that Drake punched Chris Brown in the face and before Chris could retaliate; someone hit Chris in the mouth with a bottle, bruising his chin badly.

Security swooped in and broke the fight, Drake and his crew left before the Police arrived and Chris, reports say, went to the hospital to be treated.

Chris Brown later took to micro-blogging site Twitter to rant on the incident and twitted a picture of his badly bruised chin. He later deleted all tweets.

Meek Mill some hours ago tweeted ‘It wasn’t me…. (shaggy voice) lol’.
