"She would order out for pizza, the only thing not working up a sweat was the Cristal cooled to 22 degrees," he said.
Ray J also revealed that if mom Kris Jenner called during sex, "she would nearly always take it".
But the loose-lipped musician didn't stop there, moving on to discuss her finances.
The publication wrote: "During a wild 12 hour party session, he [Ray J] also told revelers about Kim's wild spending habits - claiming she racked up around $100,000 on 'floss' - the American term for thongs."
During Ray J's night out, he also reportedly referenced his ex's current marriage to Kanye West, reciting: "I hit it first, man!" before confirming he had no regrets on his time with Kim.
The musician who currently married to stripper Princess Love, first rose to fame after his sex tape with the KKW Beauty entrepreneur.
