In a sneak peek at Sunday’s episode of Keeping Up with the Kardashians, things get personal when Kourtney Kardashian shades the momager for cheating on her father, the late Robert Kardashian Sr., with soccer player Todd Waterman.
“For some reason you do not give mum the benefit of the doubt, ever, from your childhood and it’s really unfair,” Khloé Kardashian says in an attempt to mediate the situation. “You only remember with Todd or this or that.”
“I don’t sit there and dwell about Todd,” Kourtney insists.
When Jenner, 62, claims that her eldest daughter has her “own Todd right now,” Kourtney bristles. (When the scene was filmed, she was dating Younes Bendjima.)
“No, I actually don’t. I’m actually not married, and I’m not having an affair,” she fires back. “You can’t compare one to the other. That’s absolutely not true.”
“I’m just saying sometimes our memories get a little warped by our age,” Khloé says. “Don’t be so hard on your mum.”
But Kourtney doesn’t think they’ll ever see eye-to-eye.
“I don’t think it’s even about talking to my mom about it,” she says later. “I think it’s like, we all have different experiences with my mum and I think it’s not something, really, that my mum can fix.”
Jenner and Kardashian Sr. were married from 1978-1991 and welcomed four children together: Kourtney, 39, Kim, 37, Khloé, 34, and Rob, 31. The family patriarch was diagnosed with esophageal cancer in July 2003 and died less than eight weeks later at age 59.
In an interview with Fox News Channel’s OBJECTified this summer, Jenner admitted the affair was “nothing I’m proud of.”
“When I look back on it now, probably one of my biggest regrets in my life is that that marriage fell apart,” she said.
