The "212" rapper is alleging that Russell Crowe assaulted her after the Nice Guys actor removed her from a private event at his Beverly Hills hotel room on Saturday night.
Banks, who attended the party as RZA's plus one, claims in a since-deleted Facebook message, "To recap my night, I went to a [party] at Russell crowes suite, at which he called me a n***er, choked me, threw me out and spat at me."
"Last night was one of the hardest nights of sleep I’ve had in a long time," the 25-year-old added. "The men in the room allowed it to happen. I feel terrible today."
ET spoke with Beverly Hills Police Department Sgt. George DeMarios following the incident, who confirmed, "Azealia Banks did file a report against Russell Crowe with the BHPD on Sunday afternoon. Detectives are investigating the matter."
According to a TMZ report, several eyewitnesses allege that Banks was using vulgar profanities and threatening guests before Crowe carried her out after she grabbed her glass and appeared to cock it back.
Following the alleged altercation, Banks' rep shared a statement to Twitter, writing, "Azealia is tremendously distraught and disheartened. She is shell shocked and will speak out on the incident once she has had time to process the brutality and abuse she was unjustly subjected to."
This is not the first time Banks has found herself at odds with another public figure.
