Kendall Jenner questions Caitlyn's 'insane' tell-all book

Kendall Jenner has admitted she struggled to understand why her father Caitlyn used her new book to "bash" her mom and sisters.

Reality star Caitlyn came out as a woman back in 2015 after formally living as Olympic athlete Bruce Jenner and being married to ex-wife Kris Jenner.

Her new memoir, The Secrets of My Life, has already ruffled the feathers of most of her family due to claims such as Kris knowing about Caitlyn's gender identity long before her transition and in the next episode of Keeping Up with the Kardashians, Kendall can be seen sharing her own thoughts on the tome.

“I heard about all of the stuff she was saying in it and just how a lot of it is so not true,” the 21-year-old says to her mother Kris in Sunday night's (4Jun17) episode, a clip of which has been obtained by Us Weekly. “I don’t think it’s purposeful lying. I think she really just thinks that’s what happened for some weird reason.”

Going on to discuss comments aimed at the Kardashian children, including Kris' daughters Kim and Khloe, Kendall continued, “She goes around dissing the Kardashians, but it’s like, those are the children that you raised. If you have a problem with them, you raised them. It makes no sense to me that she would go around bashing us for no reason. It’s insane, mom.”

Kris has already spoken out against the book, slamming the contents as "made up", and in the next episode of her reality show the 61-year-old notes it would have been handled in a much more "loving way".

She also insists everything written in the memoir will remain with the family forever, sighing to Kendall, “Everything was like I am such a bad person. Your children are going to read this book about their grandparent and have a story that’s fabricated.”
