CHRIS BROWN AND DRAKE GET INTO A FIGHT FOR RIHANNA

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*ckng the love of your life [Rihanna], deal with it."

Whatever message Drake sent back caused Chris to immediately fly into a rage - and he CONFRONTED Drake and his entourage - which included ANOTHER Chris Brown rival, rapper Meek Mill. Meek Mill also had a relationship with Rihanna.

Well according to our snitch, Drake PUNCHED Chris in the face and before Chris could retaliate, someone (#teamnosnitch#) popped Chris in the mouth with a BOTTLE, multiple times. And as a result, Chris was LEAKING LIKE A FAUCET!!!

Security immediately swooped in and broke up the fight. Drake and 'em immediately LEFT the club, before POLICE arrived. Chris, we're told left under his own power - and later went to the HOSPITAL, to get his face sewn shut.
