Chris Brown and Drake have reportedly been involved in a violent altercation at a New York nightclub.
According to reports, the 23-year-old R'n' B star and the 25-year-old Canadian rapper clashed in at the famed Greenhouse club over Brown's ex Rihanna.
It all apparently came to a head when the musicians, who are said to have a long-running feud over Drake's brief fling with the Bajan Beauty, came face-to-face inside the club.
Celebrity site, MediaTakeOut claims Brown sent a bottle of champagne to Drake's table as a peace offering.
However, the bottle was soon returned with a message boasting about the Young Money star sleeping with RiRi and Brown flew into rage.
An angry Brown immediately confronted the Young Money rapper which led to him being punched in the face and repeatedly hit with a bottle.
An onlooker told celebrity site Groovevolt.com: "There were bottles being thrown from Drake's entourage and some say they saw Meek Mills also throw a punch at Chris,"
"I wasn't able to see it all but it did not look good for Chris," the source added.
Following the fight, the R&B star was treated in hospital for the 2inch gash that needed stiches.
Rihanna's ex posted shared a snap of his bleeding chin with fans on his Twitter page before later removing it.
The party, attended by stars including Ne-Yo, Drake, Maxwell, Julez, Mary J.Blige, Meek Mill, Trey Songz and Maino, was to honor the birthday of a few industry favorites.
