The loose-lipped recording artist spoke to party-goers in London according to The Sun newspaper.
The couple dated from 2005 to 2007 and according to him they had a pretty wild time.
Kim and the performer infamously released a sex tape in 2007 that helped launch her career.
“Kim and I had fun times - marathon session,' he began while speaking to fans during the 'boozy' and 'wild 12-hour party session,” he allegedly revealed.
He added: “But she didn't like getting sweaty and would stop to do her makeup if she did.”
“She liked to look dope during sex, the right lighting, setting the mood. She was wild - there was a red Louis Vuitton trunk of sex toys.”
And she only ever had $300 bottles of Cristal to wash down her favorite food.
“She would order out for pizza, the only thing not working up a sweat was the Cristal cooled to 22 degrees,” he said.
The reality star also had a thing about G-strings spending $100k a year on them while making sure they were always in good condition.
During Ray J's night out, he also mocked his ex's current marriage to rapper Kanye West.
He bragged: “I hit it first, man!”
The musician is currently married to Kim lookalike, stripper Princess Love.
Kim Kardashian hit back at Ray J’s claims via Twitter.
She told her fans: “Or shows he’s a pathological liar … you actually believe this story? It’s too funny to me."
