Caitlyn Jenner’s new memoir isn’t even out yet, and it’s already tearing the family apart. The excerpts that have been released to reporters are filled with juicy revelations, including allegations that Kris Jenner's late ex-husband Robert Kardashian believed that O.J. Simpson was guilty. Let’s just say that the title The Secrets of My Life really delivers. Unfortunately for familial harmony, there are a few people who do not want their secrets spilled: the Kardashians.

Us Weekly reports that the book includes Caitlyn’s feelings about Kris, even suggesting that she forced Caitlyn to “suppress her true self.” Caitlyn apparently didn’t run the full contents of this memoir before Kris ahead of time, and honestly, why should she? Caitlyn’s her ex, not one of her daughters. But it’s causing problems.

An insider told Us Weekly that the Kardashians are fed up with Caitlyn. “Cait’s talking about the family but didn’t speak to them first, just like she did with the Vanity Fair interview,” they explained. “They’re tired of being caught off guard.”

The source added that the girls “want Caitlyn to be happy and share her experience, but also to be sensitive to Kris.”

While Kris is probably fuming, it sounds like Khloé Kardashian has also had it with Caitlyn. “This is the last straw,” said the source. “Khloé doesn’t identify with this person who seems to have stopped caring for the family.”

At one time Caitlyn was close with all of her stepdaughters, but she was also not as much in the spotlight. Shifting priorities shift relationships. Or this could all be baseless gossip. Only future episodes of Keeping Up With The Kardashians will tell.
