Chris Brown Bar Brawl—With Drake?! Was It Over Rihanna?

Chris Brown apparently had an eventful evening.

The R&B star posted a picture on his Twitter page last night that revealed a pretty gnarly gash on his chin, resulting in speculation that the cut was caused by an altercation involving bottles being thrown between Brown and fellow singer Drake and their respective entourages at a New York City nightclub.

So what supposedly went down?

E! News has confirmed with the NYPD that, at 4:08 a.m., officers responded to a call of disorderly conduct at the WIP nightclub. Five victims suffered non-threatening lacerations and were removed to area hospitals. There were no arrests and the investigation is ongoing. 

"How u party wit rich n**** that hate? Lol... Throwing bottles like girls? #shameonya!" Brown tweeted along with the photo, although both have since been removed from his account.

There are reports that rapper Meek Mill was with Drake last night as well, and rumors are running rampant that the fight may have started because both men are believed to have romanced Brown's ex, Rihanna. 

Mill has since posted a tweet this morning, saying simply, "It wasn't me... (shaggy voice) lol."

No word from Drake on his Twitter page regarding the spat. He is scheduled to perform tonight at the Performing Arts Center in Saratoga Springs, NY.

Coincidentally, Mary J. Blige, according to the nightclub, also just happened to be there, but she has yet to comment on Twitter about what may or may not have gone down.
