Named only as “Ryan” in the recently released memoir “Kris Jenner and All Things Kardashian,” Star magazine exclusively revealed the true identity of the momager’s boy toy, who was just a tender 24 at the time their 1989 tryst began.

He is renowned Hollywood animator Todd Waterman, who told Star in an exclusive interview that he and Kris Jenner shared an “intense affair.”

“It was scandalous,” confessed Todd Waterman.

“We dated for a year and a half. I was playing pro soccer and I was training with a team, L.A. Heat, for a now defunct league. That’s how we met.”

The outing of Todd Waterman is yet another twist in the paternity scandal engulfing Kris Jenner’s daughter Khloe, who is facing claims from Robert Kardashian’s ex-wives that she isn’t a biological Kardashian.

In light of the women’s sordid allegations, the showbiz world has been left to ponder who could be 27-year-old Khloe’s potential real dad if Robert Kardashian were not.

While the naming of Kris Jenner’ secret lover could provoke some to question whether Todd Waterman fathered Khloe, it’s not possible, as Khloe was aged five at the time her mother, then 34, began seducing him behind her father’s back.

Robert Kardashian, the Hollywood lawyer who worked on O.J. Simpson’s notorious dream team during the murder trial of the football star’s wife, even named Todd Waterman in his and Kris’ 1991 divorce documents, filed in the Los Angles Superior Court.

Robert Kardashian slammed Kris, writing in a declaration obtained by Star: “Your honor will recall at the time of the hearing I claimed that the respondent was involved with another man named Todd Waterman.

“I ask the court … to restrain (Kris) from living with any member of the opposite sex in or about the presence of our children.”

Todd Waterman, who now directs animated films for Disney and Columbia Pictures, said while Kris Jenner called it a “mid-life” crisis moment, their relationship was far from a passing fling.

In her tell-all book, Kris Jenner revealed that she became obsessed with a man she dubbed “Ryan” and admitted having “wild sex everywhere, all the time” in cars, pool houses and even on tennis courts.

“One minute I was making brownies for my friends and having a family barbecue, the next I was in the middle of an insanely intense affair,” Kris Jenner wrote.

“I would tell Robert I was going out to lunch and I would end up at Ryan’s apartment having crazy, fabulous sex for hours in the middle of the day. I would drop Kourtney, Kimberly, and Khloe off at school and rush straight to Ryan.

“Breakfast, lunch, and dinner with Ryan, Ryan, Ryan, Ryan.”

While Todd Waterman said he had heard rumors that Kris Jenner had exposed her philandering in her memoir, it wasn’t until he was contacted by Star this week that he realized the extent of her confession.

“My friend has sent me an excerpt from her book,” Todd Waterman told Star.

“I think I would be Ryan.”

While Todd Waterman once shared a passion for one particular Kardashian, Kris Jenner’s former lover revealed that he is far from a “fan” of the reality television family and the multi-million dollar empire they’ve built.

“I am not a fan of the whole Kardashian machine,” Todd Waterman said.

“To me, it (my partial inclusion in the book) ties into what they have already done in terms of picking and choosing what they release and how they are portrayed.”

While not happy about his inclusion in Kris Jenner’s tell-all, Todd Waterman told Star it was to be expected from a family who has used infamy to their advantage.

Todd Waterman said: “The sex tape and the murder of their friend. It (the book) didn’t surprise me.”

While Kris and Todd Waterman’s torrid affair finally ended in 1990 – just before Kris met Olympian Bruce Jenner – the affair cost the Kardashian matriarch her marriage, after Robert followed the pair and found them together.
