Another preview of the Surviving R. Kelly Lifetime docuseries premiered on People Magazine and someone close to the singer confirmed what the public already assumed.

One of the Pied Piper’s former background singers claims she saw the then 27-year-old R. Kelly having sex with a then- 15-year-old Aaliyah when they were out on the road.

“We were out on the road with Aaliyah. On a tour bus, there really aren’t many confined spaces. When you get on the bus there are bunks and so these bunks have little curtains you can pull at night if you don’t want anybody to see you sleeping,” Jovante Cunningham says in a preview of her interview, premiered on People Magazine on Monday (Dec. 31). “So, it just so happened we were all laying in our bunks and the curtains are open, everybody’s communicating, laughing. When the [room] door flew open on the bus. Robert was having sex with Aaliyah.”

Cunningham was asked to get into detail about what she saw, and she made it clear that they were engaging in sexual activities. “Things that an adult should not be doing with a child,” she replied. “I can’t stress to you how people are still suffering behind things that went on 20 years ago.”

In 1994 a marriage certificate for Aaliyah and R. Kelly was made public and stated that the late singer was 18 years old although she was only 15 at the time.

In more recent years, multiple women have accused him of sexual misconduct and even being held against their will.
