R. Kelly is facing more allegations sexual abuse in a new documentary, in which one the singer's ex-girlfriends details a “sex dungeon” where he trained women — including a 14-year-old girl — to be his “pets.”

The doc, R. Kelly: Sex, Girls and Videotapes, which airs tonight (March 28) on BBC Three, features Kitti Jones, who dated R. Kelly for two years from 2011 to 2013. During that time, Jones said R. Kelly was “very abusive, physically, mentally, verbally,” and that he forced her into having sex with him and other people on more than 10 occasions. Jones went on to recall a “sex dungeon” where she encountered a young girl.

“I was introduced to one the girls, that he told me he ‘trained’, since she was 14, those were his words,” Jones recalled to reporter Ben Zand in the documentary. “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 his pets, he calls them his pets.”

On one occasion, Jones said that R. Kelly had the teen “crawl on the floor towards me and perform oral sex on me, and he said, 'This is my fucking pet, I trained her. She’s going to teach you how to be with me.”

In addition to Jones' recollections, R. Kelly's TP2 studio engineer, James Lee, spoke out on his experience with the “revolving door” women that R. Kelly would have come through the studio. Lee detailed the two lounges R. Kelly had as part his studio setup, one which was his fice and the other included a queen-sized sa bed — in which there was seemingly a woman at all times. He also compared R Kelly's treatment women to eating a Big Mac: “When he’s done eating you, he throws the wrapper away.”

R. Kelly's alleged illegal marriage to Aaliyah was also addressed in the documentary, as the singer's ex-manager Rocky Bivens revealed that he was actually in attendance for the 1994 ceremony between a then 27-year-old R. Kelly and then 15-year-old Aaliyah.

R. Kelly has been facing allegations since the reported wedding to Aaliyah, including more accusations having sex with underage girls, possessing child pornography, and, most recently, having an abusive sex “cult.” He has denied all the allegations.
