Kris Jenner has branded Caitlyn Jenner "mean-spirited".
In the latest episode of 'Keeping Up With The Kardashians' the 62-year-old businesswoman finally opens up about how she feels about her ex-husband's memoir 'The Secrets Of My Life', admitting it had hurt her.
The episode showed the family going for formal media training for the first time.
But Kris told daughter Kim: "I don't want to do it. I don't want to be on the defensive about us or about Caitlyn. ... I am enjoying private life to be private, more off-camera when we're not doing our show."
Later in the show the staff at Clarity Media Group grilled Kris about her 24 year marriage to 68-year-old Caitlyn - formerly Olympic athlete Bruce Jenner before undergoing gender reassignment surgery - and asked her if she had "turned a blind eye" to Caitlyn's gender identity issues.
Kris replied: "No ... I just think I didn't have the whole truth of what was going on in his life." Kendall jumped to her mother's defence, saying: "We kept a lot of it from you."
Kris claimed her children had been "told not to" repeat certain things to her.
She added: "There were things that happened that they did not tell me. I would do anything for my kids. Had I known any of the things they were experiencing ... it just broke my heart."
Speaking about Caitlyn's claims in her memoir, Kris said there we "two truths," adding that for "more than half the marriage it was like ... perfect."
And of Caitlyn coming out as transgender, she said, "I wouldn't have seen that truth in, like, a gazillion years."
Kris admitted she thought Caitlyn's book was "very mean-spirited."
She added that there were "a lot of inaccuracies," and that she wished Caitlyn had simply written, "Married to her. Didn't work out. She's a great girl."
Kris's frank comments come after Caitlyn accused the Kardashian family of "bashing" her.
The 68-year-old television personality has slammed her ex-wife Kris and her famous family, claiming that her step-children, Kourtney, Kim, Khloe, and Rob Kardashian, have pushed her out of their lives.
She said: "They don't want me in their lives, they bashed me pretty badly. It's devastating when your kids do that. It really hurt."
