In what is the latest sexual misconduct accusation against R. Kelly, the singer has now been accused training a young girl to be his sex slave since she was 14.

In a BBC3 documentary, R Kelly: Sex, Girls and Videotapes, Kelly's former girlfriend Kittie Jones says he trained her to be his "sex pet" from the age 14. Jones, now 34, says she was "groomed" to have sex with him and others in a "sex dungeon."

"I was introduced to one the girls, that he told me he 'trained' since she was 14—those were his words," Jones says. "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."

R. Kelly has refused to comment on the documentary.

For over a decade, Kelly has been dogged by accusations sexual misconduct. In 2008, he was found not guilty child pornography charges. Just last year, he was accused running a sex cult out his Georgia home (he's since been evicted). Protests against the singer have been held outside several his concerts in the wake the string allegations.

Back in January, protestors held a "March for Black Women" outside  R. Kelly's concert at FREQ and Highline Theaters in New York City. The event, organized by Black Women's Blueprint, was part the #MuteRKelly movement, which aims to support the women who have allegedly been abused by the singer, and encourage people to boycott his appearances and disengage from supporting his music.

The documentary is set to air today.
