Khloe Kardashian calls out Kris Jenner for CHEATING on her dad leaving her totally gobsmacked… after matriarch championed Tristan Thompson following his love rat antics

Khloe Kardashian mentions closet skeleton Kris Jenner — the affair she had with Robert Waterman that ended her marriage to Robert Kardashian — in a preview for next week’s episode of Keeping Up with the Kardashians.

Jenner, 67, was married to attorney Robert Kardashian – Kourtney Kardashian, father of Kim Kardashian and Khloe Kardashian – from 1978 until 1991, when they divorced.

Jenner — who, according to an exclusive Daily Mail report, treats ex Caitlyn Jenner like she’s no longer alive — revealed in her 2011 memoir, Kris Jenner… and All Things Kardashian that she cheated on Robert in 1989 with a producer named Ryan Lowe, although it was later confirmed that she was hiding his identity and was actually having an affair with a football player named Todd Waterman.

During a preview for next week’s episode, Khloe calls out Kris for cheating on her dad … after she complimented Tristan on many things, but seemed to give him a pass for repeatedly cheating on Khloe.

Khloe confronts Kris, saying: ‘Whenever you’re ready to admit you fucked me…’, but Kris says: ‘I didn’t fuck much.’

‘I’ve never heard, we put a Band-Aid over a bullet hole…’ as Chris insists, ‘No, you’ve got it wrong because you’re just somewhere else. You are spinning.’

Khloe says in the confessional: “Where I am with Tristan has nothing to do with what I expect from my family members.

Khloe drops the bomb and asks Kris, ‘What was your mindset when you cheated?’

Stunned, Chris asks, ‘Are you asking me?’

‘Who the hell am I still talking to?’ Khloe asks when the review is coming to an end.

Earlier in the episode, Chris admitted, “We know Tristan has made some mistakes. I know he is truly sorry for the way he hurt Khloe and I’m sure he regrets those mistakes every day.’

In the kitchen, Tristan says, “the kids grow up fast, they love to drive in the morning, they go to school.”

Kris adds in the confessional, “Really the most important thing for everyone right now is raising those kids, and I’m worried that Khloe, with this change of Tristan moving out, there’s going to be a void there.”

Kris tells Tristan that “kids remember all that stuff,” adding that she’s also “emotionally invested, especially in True’s class. There was one kid who was so aggressive and I was just going to say, “Listen a minute…” and then I said, “No, that’s probably not a good idea. That’s not your child.” Your grandmother is a bully.’

Waterman came forward in 2012 as the man with whom Jenner had an affair, more than 10 years after Kris and Robert married.

At the time, Waterman was a 23-year-old soccer player with the Los Angeles Heat, though he later transitioned to an Emmy-winning animation career.

He revealed that Robert had hired private investigators and confirmed that Chris had cheated, and Waterman claimed in a 2012 interview that Robert went after him with a golf club.
