In a series of status updates late Saturday night, Banks said Crowe — who has been accused of using racist language before — choked her before throwing her out of his hotel suite.
In another post Banks said, "just feel so low and mishandled and alone and fucking depressed right now. I wish I had someone to beat him up for me" and that she wanted to die.
Banks left one post up, claiming she has proof of the incident.
According to TMZ, however, witnesses said it was Banks who used the racial slur, not Crowe, and that she was behaving "erratically" at the party and threatened to cut guests with glass.
"You would love it if I broke my glass, stabbed you guys in the throat, and blood would squirt everywhere like some real Tarantino shit," Banks reportedly said before being thrown out of the party.
Banks has had a history of using derogatory and racist language, which got her banned from Twitter in May.
