Graphic details were released Wednesday in the case against R. Kelly as one of his alleged victims took the stand.

Jerhonda Johnson Pace, 28, said she began a sexual relationship with the singer when she was only 16 years old.

Pace is one of the women who participated in the Lifetime documentary, “Surviving R. Kelly.”

Pace testified that she began a relationship with the singer, whose real name is Robert Sylvester Kelly, when he invited her to his home in the Chicago suburbs in 2009.

Pace said when things began to get physical between the two, she told him she was a minor, to which he expressed not caring. She said the two performed oral sex on each other and Kelly took her virginity.

Pace says whenever she was at Kelly’s home, she was unable to leave the room she was in, and wasn’t allowed to have a cellphone.

Pace said their relationship ended after 6 months. Pace testified that when she didn’t acknowledge Kelly as he walked into a room, he allegedly slapped her and choked her “until she passed out.”

Other women have shared similar encounters of being locked up and abused.

Kelly, who is now 54 years old, has pleaded not guilty to charges of racketeering and violating the Mann Act, an anti-sex trafficking law.

Separately from this case, Kelly faces federal child pornography and obstruction charges in the Northern District of Illinois, and faces state charges there for multiple counts of aggravated criminal sexual abuse. He has strongly denied the accusations.

Now Pace did a Monica Lewinsky…and kept an item of her clothing — a tshirt — which still has Kelly’s DNA (semen) on it.

This is all a sticky situation no matter which side you believe. We will keep you posted with updates.
