Caitlyn Jenner Upsets Kardashians Over Her Memoir, Cries “Foul” Over “Unflattering, Unfair Portrayal” Of Matriarch, Kris Jenner, Surprise Revelations

Caitlyn Jenner, the patriarch figure of the popular Jenner-Kardashian clan, recently released a memoir about his life. Titled “The Secrets of My Life,” several choice excerpts have been published exclusively both in the latest print and on PEOPLE.com.

One of the many revelations on Jenner’s memoir includes her confession to wearing ladies’ underwear underneath her business suits, when she was still known as the 1976 Olympic gold medal winner Bruce Jenner. Following her win, the former Bruce went on a motivational speaker circuit. But unknown to many, he was already carrying something else.

“They don’t know that underneath the business suit I am wearing panties and a bra. That I am not Bruce Jenner but a woman I will come to call Caitlyn, who still has to be Bruce except for stolen moments where I can be my authentic self. The speech that I give is called ‘Finding the Champion Within’. All bulls—,” she wrote.

Although some would applaud Caitlyn’s honesty, the Kardashians? Not so much, according to multiple reports. In a new promo clip of the family’s reality show “Keeping Up With the Kardashians,” Kris expressed her frustration about Caitlyn portraying her as something she says she’s not. Talking to daughters Khloe Kardashian and Kim Kardashian-West, she said, “Basically the only nice thing she had to say was that I was great, socially, at a party one time. None of it makes sense. Everything she says is all made up. Why does everything have to be that Kris is such a bitch and an asshole?”

Another source also said that Caitlyn catching the family offguard has put a wall between them. Khloe, who is notoriously close with Caitlyn, is supposedly done with her stepfather.

“This is the last straw. Khloé doesn’t identify with this person who seems to have stopped caring for the family,” the source added.
