Mel B's Ex Stephen Belafonte Says She's a Lying Drug Addict and Alcoholic

Mel B is a drug addict and alcoholic who has walked into doors and has been hospitalized for ODs, and she has covered up the bruises and other injuries from her addiction by claiming it was domestic violence ... so says her ex-husband, Stephen Belafonte.

Belafonte just filed legal docs in an effort to get visitation rights in connection with his stepdaughter, Angel, whose biological father is Eddie Murphy. Belafonte, who has been with Angel almost since her birth, claims Mel B is concocting lies about domestic violence to turn Angel against him.

He refers to a 2014 incident in London where Mel B claims he bashed her head into a door. Belafonte says, in fact, what happened was that Mel B ODd on drugs, was hospitalized and sustained bruises from the EKG machine and IV during her stay in the hospital, and falsely claimed it was the result of abuse.

He says she is so addicted to drugs and alcohol she walks into walls because she's drunk in the middle of the day. He says she is so wasted sometimes she will pull down her pants and try to urinate on the couch in front of the kids.

He also notes in his legal docs, obtained by TMZ, her claims that he forced her to have 3-ways is a lie. He says he has videos where Mel B initiates and records the trysts and looks into the camera and says, "That's hot!" and "I like it."

Mel claimed in docs Stephen showed the kids ISIS beheadings. He says this is a blatant lie and he hasn't even searched for such videos.
