Kris and Caitlyn Jenner forced their children to choose between them when they split.
The former couple - who were married for almost 24 years - officially divorced in March, just before Caitlyn came out as a transgender woman and their 19-year-old daughter Kendall claims they made her and her sister Kylie, 18, take sides.
In a teaser for the upcoming series of 'Keeping Up With The Kardashians', she said: "Dad and mom put me and Kylie into choosing between them."
Kris previously lashed out at Caitlyn, telling her to "go f**k himself".
She was furious with her ex-husband - who was known as Bruce before he transitioned - after she accused her of bullying her during their 24 years of marriage in her first interview as a woman.
Speaking about the July issue of Vanity Fair magazine, Kris fumed: "It just sums up that I'm this piece of s**t person who was mean. He can go f**k himself. I honestly wish I never met this man."
And Kris' daughter Kim Kardashian West, 35, wasn't happy with her step-father's comments in the interview.
She said: "All Caitlyn can talk about is that my mom mistreated her and was awful, and just all these really rude things when there's no reason to bash my mom"
Younger sister Khloe, 31, agreed.
She chipped in: "Don't discredit all these children that you guys brought into the mix. We don't believe in bashing anybody. We don't bash any parents. I expect her to do the same."
