According to police, Brown was involved in an argument with her unidentified boyfriend around 5:30 am in the Louis H. Pink Houses in East New York.
The man called four prostitutes, who allegedly attacked Brown, ripped out her hairweave, stole her hearing aide, her purse and $500 dollars.
Now, Brown is denying the altercation ever happened.
"I have friends all over Brooklyn but I was not there last night," Brown told The New York Post. "I just got back this morning from Miami….a lot of the time people mistake me for someone else or people always call in these false tips. I don't know why. I guess it's just part of being a celebrity."
Although Brown allegedly pointed Anthony out to police shortly after the assault took place, the rapper has since stopped cooperating with police.
Police say Brown was indeed assaulted and have charged Roshawn Anthony, 23, with robbery and assault.
They are also looking for the three other women involved in the attack.
Anthony is a hooker who was allegedly forced into prostitution by an abusive lover, according to the woman's mother.
She is currently being held on Rikers Island in lieu of $50,000 bail.
Although Brown has denied the assault charges, she gave reporters a message as she left her Brooklyn brownstone for a tour a show in Jamaica.
"We love the controversy," Brown told reporters. "Keep writing."
The incident comes on the heels of Brown's probation being upgraded to good status, after she was arrested for assault in Feb. in Pembroke Pines, FL, after being involved in an altercation with the owner of a beauty supply store.
She currently faces a September trial for battery and resisting a police officer with violence in connection with the Florida altercation.
Brown has pleaded not guilty.
