RZA, 47, brought Banks to the intimate dinner party thrown by Crowe as his plus-one, reported Entertainment Weekly.
Banks has filed a police report, claiming she was "spat on, choked, thrown out of a room at the party".
"Before the night is over Azealia is insulting half the room she becomes loud and obnoxious. There was nothing funny about her behavior. I felt a little embarrassed because she was my guest. Azealia threaten (sic) to cut a girl in the face with a glass, then actually grabs a glass and physically attacks for no logical reason. Russell blocked the attack and expelled her from the suite.
Banks, 25, has responded to RZA saying he is trying to "gaslight" her. The singer also took to her Facebook page to reply to the allegations made by RZA.
"RZA has clearly been given no legal advice and went to out his feelings to try and gaslight me. Whatever pieces are left of his brain after years and years of smoking dust stupidly allowed him to ramble himself into incriminating his friend, and completely debunking their entire made up theory.
