The Wu-Tang Clan rapper posted a lengthy Facebook status on Thursday, refuting many of the things Banks -- who RZA brought to the party -- said happened on Saturday night at a private party in a Beverly Hills hotel room.
In the post, the 47-year-old artist says that he had only associated with Banks on a professional level before, on his film, Coco, which he adds went "smooth" despite the fact that he allegedly had to fight for her because of "rumors of her problems in the industry."
"Therefore 'I HAD NO REAL EXPERIENCE OF HER SOCIAL BEHAVIOR...'" RZA exclaims.
"Before the night is over Azealia is insulting half the room she becomes loud and obnoxious," claims RZA of Banks' behavior at the party. "There was nothing funny about her behavior. I felt a little embarrassed because she was my guest."
"Azealia threaten[ed] to cut a girl in the face with a glass, then actually grabs a glass and physically attacks for no logical reason," he alleges. "Russell blocked the attack and expelled her from the suite."
RZA claims that Banks' behavior was so "erratic" that he "thought maybe meds or booze or something had her zoned out. Nevertheless I made sure she got home safe."
"THIS IS NOT A RACE OR GENDER ISSUE," the rapper emphatically says, responding to Banks' claims about racism and sexism causing her dismissal, before also responding to her accusation that Crowe referred to her using a racial slur. "I did not hear Russell call her a [N-word]."
"I'm not trying to protect Russell from anything he is a man of his own Caliber," RZA concluded the post. "My art, talent and success speaks for it self and Azealia's recent slander of me and self victimization reflect's the personality of the person that was in that room that night. I have a wife, daughters, sisters and females on my staff so I protect women everyday. I pray none of them ever behave the way I witnessed Azealia Banks behaved that night."
It should be noted that while RZA has maintained that Banks was the instigator, and that Crowe stayed calm, he did tell TMZ in an interview that the actor spit in her direction after she'd been removed from the room.
RZA makes other claims in the post, including that Banks asked for his help getting a record deal prior to the incident, and that one had not yet been reached when she posted about it on social media.
Banks maintained her allegations in a TMZ video after the incident that she was "choked, spit on, and called a [N-word]," during the party.
Banks also claimed that RZA "stood there like a chump," and didn't back up her claims because he "doesn't have that much clout in a room full of real, high-powered Hollywood white men."
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."
ET also reached out to Crowe's rep after the alleged altercation.
