UPDATE: Chris Brown's representatives have responded to the allegations, calling them "totally false." In a statement to USA Today, Brown rep Nicole Perna says, "Upon speaking with witnesses, security and the owner of the club, it has been proven that said patron caused the physical harm to herself in her belligerent state."

PREVIOUSLY: A 24-year-old woman is accusing singer Chris Brown of allegedly assaulting her on Saturday after his show in an Orange County nightclub.

The woman, Deanna Gines, says as the Heat Ultra Lounge was closing, Brown reportedly knocked her to the ground, badly injuring her knee. According to Gines, doctors have told her there are torn ligaments in her knee and that she may need to have an operation.

Though nothing has yet been substantiated, Brown has had a string of assault accusations and unfortunate club encounters which don't help the singer's situation.

In January, Brown, 24, had an altercation with Frank Ocean which has yet to be put to rest completely. In March, Brown and his crew were reportedly involved in a bottle-smashing brawl with Drake and his crew. Not to mention the most obvious, his now infamous 2009 incident with singer and then-girlfriend Rihanna.

Chris Brown's rep has yet to respond to the allegations.
