Kim Kardashian claims parts of Caitlyn Jenner's tell-all aren't truthful

Caitlyn Jenner included several critical passages in her new memoir about the K-troop, her nickname for the Kardashian clan, in particular, momager-in-chief Kris Jenner. So it should come as no surprise that the Ks aren't exactly here for it.

In a clip from Thursday's Ellen DeGeneres Show, the K front-woman questioned why her former stepparent would choose to air what seems to be some of the family's dirty laundry.

"My heart breaks for my mom, you know, because I feel like she’s been through so much and she's promoting this book and she’s saying all these things,” Kim said, referencing Jenner's book tour. “I don’t think it’s necessary and I just feel like it’s unfair, things aren’t truthful.”

She went on to confirm that she thinks Jenner isn't being honest in regard to Kris.

In the book, Jenner all but says how much her then-wife knew about her gender dysphoria, which contradicts some of Kris's past comments on the subject.

"I tell Kris about my gender issues before I make love to her," she writes.

And implies their marriage was one of mutual convenience.

"Kris restores my credibility. She helps to restore the image of Bruce. I also believe, and once again this is my opinion only, that Kris gets something from me," she writes, referring to rumors and some close calls of people finding out that she was on hormone therapy in the late 80s. "So sometimes I wondered if Kris was making a statement to her former husband: a big (expletive) you."

Though Kim doesn't specifically identify which parts she believes are inaccurate, she explains a little about why it's upsetting.

"I feel like it's taken a really long time for her to be honest with herself so I don't expect her to be honest about my mom now," she says. "Tell your story, but just don't bash other people."
