In her memoir, mum Kris Jenner admits she had an affair with a man called 'Ryan', which ended her marriage to Robert Kardashian in 1990.
Hollywood animator Todd Waterman has now stepped forward, claiming to be 'Ryan'.
Waterman says he was 24 at the time and playing pro soccer when the affair began in 1989. He decided to cash in come forward after reading Kris's book and realising that the man she'd dubbed 'Ryan' was actually him.
“It was scandalous, we dated for a year and a half,” he told Star magazine.
Kris wrote in her memoir, "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.
Robert eventually caught his wife cheating after following her to her lover's apartment. He filed for divorce, and Kris continued seeing 'Ryan' (Todd?) until 1990 when she met her current husband, Olympian Bruce Jenner.
Many blogs and magazines are now speculating that this Todd Waterman guy could be Khloe's real father, but considering she was born in 1984, he would've had to have met Kris quite a few years earlier – when he was only 19 years old.
Hmm, it's not looking too likely. Although we can see a slight resemblance, don't you think?
