R. Kelly's former 17-year-old live-in lover testified they had sex without using protection and he gave her a painful sexually transmitted disease.

Jane Doe number 5 testified during Kelly's ongoing sex trafficking trial at the Eastern District of New York courthouse in Brooklyn on Monday.

Taking the witness stand, Jane Doe number five, who allegedly dated the singer for five years, revealed she first met Kelly in 2015 at a show in Florida when she was 17.

She explained someone from his entourage handed her a piece of paper with his cell phone number written on it, and told her not to tell anyone about it. Kelly then offered her an audition to sing for him and she met up with the star days later, when he allegedly performed oral sex on her.

The unnamed accuser then told the court that Kelly's assistant booked plane tickets for her so she could visit the singer on his tour stops. She insisted the aide knew she was only 17.

Jane Doe claimed when she first had sex with Kelly, he didn't use protection or disclose his STD.

Kelly's physician of 25 years earlier testified that Kelly had genital herpes since 2007.

Jane Doe said she moved in with the singer at his leased mansion in Atlanta, Georgia. There, he demanded she get permission from him or his assistant before leaving a bedroom and made her urinate in a cup.

Jane Doe testified she and Kelly had sex almost every day during the summer of 2015, and he videotaped their sessions.

She said she discovered she had contracted herpes from Kelly when she "couldn't physically even walk." Testifying through tears, she told the court, "I felt this man had purposely given me something he knew he had".

Jane Doe revealed she and Kelly received a letter of consent from her mother in September, 2015, allowing the 17-year-old to live with him and be home-schooled in Chicago, Illinois.

She testified Kelly flew her to tour stops, and she became pregnant in 2017. She was pressured to have an abortion by the star's assistant.

She also claimed the singer told another live-in girlfriend he married late singer Aaliyah, when she was 15, so he could accompany her to get an abortion when she fell pregnant.

Her testimony follows several days of similar claims from other women.

In earlier testimony, Kelly's former assistant said he paid $500 to bribe a court worker to obtain a marriage license for 15-year-old singer Aaliyah to marry Kelly because he feared she was pregnant.

Kelly was arrested over 2 years ago in Chicago and extradited to New York to stand trial. He has pleaded not guilty to the sex trafficking charges. He faces up to life in prison if found guilty on all counts.
