In the new documentary R Kelly: Sex, Girls, and Videotapes, the R&B star is being accused of sexually abusing an underage girl. In the BBC3 program, R. Kelly's former girlfriend Kitti Jones made the claims after admitting to being his sex slave for two years.

"I was introduced to one of the girls, that he told me he ‘trained’ since she was 14, those were his words. I saw that she was dressed like me, that she was saying the things I’d say and her mannerisms were like mine," she said. "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."

According to Kitti, R. Kelly would make the unnamed woman "crawl on the floor towards me and perform oral sex on me, and he said, ‘This is my f–king pet, I trained her. She’s going to teach you how to be with me.’”

This is the latest in a string of sex scandals involving the "I Believe I Can Fly" singer. In 2008, R. Kelly was found not guilty of child pornography charges after he allegedly videotaped a sexual encounter with another 14-year-old. He also controversially married a then 15-year-old Aaliyah seven years before her death in 2001.

More recently, he was accused of brainwashing women in a "sex cult" in an investigation by Buzzfeed. "[She] looked like a prisoner — it was horrible,” said a mom whose daughter is reportedly controlled by R. Kelly. “I hugged her and hugged her. But she just kept saying she’s in love and [Kelly] is the one who cares for her. I don’t know what to do. I hope that if I get her back, I can get her treatment for victims of cults. They can reprogram her. But I wish I could have stopped it from happening.”

R. Kelly has never responded to the accusations, but his attorney Linda Mensch has defended her client in the past. "We can only wonder why folks would persist in defaming a great artist who loves his fans, works 24/7 and takes care of all of the people in his life,” she wrote. "He works hard to become the best person and artist he can be. It is interesting that stories and tales debunked many years ago turn up when his goal is to stop the violence; put down the guns; and embrace peace and love. I suppose that is the price of fame. Like all of us, Mr. Kelly deserves a personal life. Please respect that."
