Warning: The following story contains graphic descriptions of sexual abuse.

NEW YORK Jane Doe and her parents met R. Kelly at one of his concerts in 2015, when Doe was just 17 years old and the R&B singer was 48. Doe, now 23, testified anonymously Monday in the R&B singers sexual abuse trial, describing harrowing sexual, physical and mental abuse she says she experienced during their five-year relationship.

Doe, formally referred to as Jane Doe No. 5 in Kellys federal indictment, gave emotional testimony at the Brooklyn Federal Courthouse and discussed in detail the abuse she says she endured at the hands of the R&B singer, whose full name is Robert Sylvester Kelly.

She cried multiple times on stand while testifying that Kelly imposed strict rules, including making her call him Daddy and controlling what she wore and ate and where she was allowed to travel. Doe said Kelly made her have sex with several other women during their relationship and often collected collateral on her like recording a video of her lying and saying her father molested her so she was unable to leave the singer.

Doe, who met Kelly during her junior year of high school, had a sexual relationship with the singer throughout the summer before her senior year. She ended up moving to Chicago for her senior year of high school and lived with him while she took virtual classes.

Her testimony painted a powerful picture of a predatory lifestyle. The singer faces eight counts of violating the Mann Act, which prohibits taking minors across state lines for the purpose of prostitution, and one count of racketeering. Prosecutors hope to show that Kelly and his entourage acted like a criminal enterprise, using the singers fame and power to recruit underage girls and boys so that Kelly could sexually and physically abuse them. Kelly did engage in sex with Doe when she was 17, she testified, which constitutes rape in Florida and California.

Kelly used his success to lure Doe and her family into his world, according to Does testimony. A few days after they met at his concert in Florida in 2015, he invited her to his hotel room, where he told Doe, an aspiring musician, she could audition for him. Once there, however, he said he needed to ejaculate first before he could hear her sing.

I was against it, Doe told prosecutors. I told him I did not come to please him and that I was coming to audition. Kelly continued to pressure Doe, who eventually caved and let him give her oral sex before he allowed her to sing for him.

Ten days later, Kelly had an assistant book flights for Doe to travel to Los Angeles and meet him at one of the stops on his Black Panties tour. From there she traveled to other parts of the country to visit Kelly on tour stops. Eventually, Kelly had sex with Doe, who was still a minor at the age of 17. All of Does interstate travel was paid for by Kelly and booked through one of his assistants. This part of Does testimony will likely play a big role in prosecutors evidence of racketeering.
