After claims of running an abusive sex cult in his Georgia home surfaced last year, R. Kelly is back in the hot seat for his alleged treatment of women. A new documentary on BBC titled R Kelly: Sex, Girls and Videotape paints a stomach-turning picture of the R&B crooner's life behind closed doors, as multiple people from his past come forward to share new information.

The documentary, which features reporter Ben Zand interviewing people from the musician's past, dives into multiple abuse allegations, such as the ones that previously came from Kelly's ex-girlfriend, Kitti Jones. If you recall, she spoke out about the alleged abuse she endured from the singer in the past, claiming that it drove her to the brink of suicide.

In the documentary, she says that R. Kelly was abusive "very abusive, physically, mentally, verbally," and claims that he trains underage girls like pets, and was grooming her to become one. She then explains what happened while being introduced to one of the girls, who dressed and spoke just like her.

"I was introduced to one of the girls, that he told me he "trained" since she was 14. Those were his words," she says, according to the Daily Mail. "I saw that she was dressed like me, that she was saying the things I'd say and her mannerisms were like mine. That's when it clicked in my head that he had been grooming me to become one of his pets, he calls them his pets."

Describing it as being like a "sex dungeon," Jones also claims that Kellz forced the girl that the singer had "trained" to "crawl on the floor" and perform oral sex on her. She alleges that he then told her, "This is my f****** pet, I trained her. She’s going to teach you how to be with me."

Another person from Kelly's past featured in the documentary studio engineer James Lee, who describes the singer as having a "revolving door" of women who would join him during his studio sessions. Lee claims that Kelly would pick up women to bring back to the studio from a local McDonald's, and described his treatment of girls as being like a "Big Mac" that he would throw away when he was finished.

"They were mostly from the areas he grew up in. He would occasionally go to this McDonald's and come back to the studio with a girl or two," he continues. "[Kelly] could be controlling. They’re there for one thing, they’re there to service Rob. When he was tired of you, you’re a Big Mac – when he’s done eating you, he throws the wrapper away, thank you."

One of the singer's former backup dancers, Lovell Jones, also addresses Kelly's alleged treatment of women, claiming that he is "conflicted" due to him being a spiritual person, but also "perverted." He even describes the singer as being like a "Jekyll and Hyde" character.

The documentary also interviews Kelly's former business manager, Rocky Bivens, who confirms that the vocalist did marry Aaliyah back in 1994 when she was just 15 years old. He says that the wedding did take place, which he was in attendance for at the time when R. Kelly was 27 years old.

Last year, many accusations from family members and those who claimed to have previously stayed with R. Kelly at his different homes came to light. He even got paid a visit by police who were doing a welfare check on behalf of one of the families of one of the women who is reportedly staying with him. Since then, he has denied the claims and has not been charged with any crime.
