Khloe Kardashian has confronted Kris Jenner over her infidelity.
The 39-year-old star asked her mom about her cheating on Robert Kardashian - Khloe's dad and Kris' ex-husband - during a heated exchange on an upcoming episode of 'The Kardashians'.
In a teaser of the next episode, Khloe says: "Whenever you’re ready to admit to me that you f***** up big time with me..."
Kris, 67 - who was married to Robert between 1978 and 1991 - then fires back: "I did not f** up big time."
Khloe subsequently complains that she's "never f****** heard".
She adds: "We put a Band-Aid over a bullet hole."
Kris replies: "No, you misunderstood. You’re just somewhere else, you’re spiralling."
Khloe - who previously split from Tristan Thompson after it emerged that he'd been unfaithful - later asked her mom to explain her own infidelity.
The reality TV star - who has True, five, and Tatum, 13 months, with Thompson - said: "What was your mindset when you cheated?"
Kris appeared shocked by the question and then replied: "You're asking me?"
Khloe snapped back: "Who the f*** else am I talking to?"
Robert died of cancer in July 2003, aged 59.
Kris met Caitlyn Jenner on a blind date in 1990 and the former Olympian recently admitted that it was a case of "love at first sight".
The 73-year-old TV star - who was known as Bruce Jenner at the time - revealed that they developed an instant chemistry, even though she was still married to Robert.
Caitlyn - who was married to Kris between 1991 and 2015 - told The Times newspaper: "We hit it off right at the beginning, and we were married after five and a half months. I was infatuated with her, because she was very different from me. But yes, I’d have to say, it was love at first sight."
