Porsha Williams is opening up about her "traumatic" experience at R. Kelly's home in her new memoir, "The Pursuit of Porsha," which is slated to release on Nov. 30.

The 40-year-old reality TV personality claimed that she was traumatized after Kelly, 54, trapped her in his mansion and pressurized her to get sexually involved.

Williams recalled that she was 25-year-old at that time. "I've already put myself in this position," she wrote in the book, PageSix reported. "This is what you're supposed to do. You have to."

Though Williams was financially independent at the time, she was mentality "conditioned over the years by men — that they are better" than her.

"And I only have value if they say I have value," she added. "I think me being in that weakened mindset made me ready and available for him to be a predator, and seek me out."

She explained that Kelly — who was found guilty in September to nine federal charges related to sex trafficking and racketeering — was not the only one who took advantage of her in her life. The singer was sentenced to 10 years of prison.

"It's not just that he was R. Kelly," Williams explained. "It's just in my life at that moment, it was just yet another man in the same position doing the exact same thing taking advantage of me."

The TV star recalled that there were "twenty or thirty other girls" at Kelly's house party when she visited him last time. Williams even heard beating sounds and girls screaming. She left the party immediately and said, "I'm done with you" when Kelly approached her again.

"The Real Housewives of Atlanta" star noted that her experience with Kelly was traumatizing, especially the last encounter.

"When I got home from that last encounter, I knew I had hit a wall," she said. "And I was completely traumatized, completely confused about why this was now happening to me again as a grown woman."

After many years, Williams encountered the singer again in 2015 when he appeared on the "Dish Nation" show, which she used to host. However, Kelly didn't remember Williams and tried to talk to her again.

"What is so freaking crazy is that he literally tried to talk to me again!" Williams explained. "And I thought to myself, 'Oh my god. I went through one of the most traumatizing experiences in my life at your home with you, and you don't remember me? This has happened that many times that you don't remember that I'm that same person?’"

Williams was last seen in a TV series, "Insecure," which was dropped in 2020.
