R Kelly, the reprehensible genius behind the Trapped in the Closet series and a plethora of songs about having sex with things, is facing mounting evidence in his child pornography trial, which will begin jury selection later this week.

The singer is facing a host of charges stemming from a video said to portray him having sex with and urinating on a 13-year-old girl. Though the alleged victim of Kelly’s abuse — now 23 — has for years denied a sexual relationship with Kelly, a new female witness for the prosecution will reportedly admit to having a threesome with Kelly and the underage girl.

In the past, three other women have filed civil suits against Kelly in which they claimed to have had sex with him before they were 17, and a fourth was paid a settlement to not sue. In 1994, a 27-year-old Kelly illegally married the now late Aaliyah, who was then then 15, by falsifying the marriage license and claiming she was 18 years old.
