Kendall Jenner is not happy about Caitlyn Jenner's new tell-all book.

Another day, another Kardashian-Jenner drama.

Kendall Jenner is not at all happy about Caitlyn Jenner’s new tell-all book ‘The Secrets of My Life’.

In a sneak peek of an upcoming episode of Keeping Up With The Kardashians, Kendall tells her mum Kris that the whole thing is “insane”.

“I spoke to Kim [Kardashian] about dad’s book and I heard about all the stuff she was saying in it, how a lot of it’s so not true,” she says.

“The weird part is I don’t think it’s purposeful lying I think she really just thinks that’s what happened for some weird reason,” Kendall adds.

Kris says Caitlyn could have handled it in the most "amazing, loving way" by just talking about her own journey, but instead she's turned it into something negative.

Kris then calls the memoir "a fabricated story” that “will be printed until the end of time”.

"So your children are going to read this book about their grandparents and have this story that's fabricated - that's in print and is a fabrication," she tells Kendall.

Kendall agrees and vents her frustrated at Caitlyn's treatment of the Kardashians.

Why the Keeping Up With The Kardashians ratings go down when the show is sad. Post continues...

“She goes around dissing the Kardashians — the kids that you raised!" she says.

"If you have a problem with them, you raised them! That makes no sense to me that she would go around bashing them and us for no reason. It’s insane mum, that’s insane."

Jenner's memoir The Secrets of My Life was released earlier this year and the Kardashian drama will continue until the end of time.
