According to a definitely unsolicited and unauthorised biography of the Kardashians, Kris Jenner advised her then-husband Bruce Jenner to suppress his gender identity struggle during their marriage.

Author Ian Halperin writes in Kardashian Dynasty: The Controversial Rise of America’s Royal Family that before she transitioned, Kris advised Caitlyn that religion could “cure” her desire to be a woman.

Kris and Caitlyn Jenner were married for 22 years before they separated in 2013 and Kris allegedly "influenced [Bruce] to suppress his desire to be a woman for all those years."

Halperin spoke to an NCAA coach who had known Caitlyn Jenner for years who said of Kris, "she told him he should pray" and that "the church could help heal him".

Shortly after their separation, Caitlyn revealed her lifelong gender identity struggle and finally underwent various surgeries last year.

Kris Jenner insisted she had no idea about her former husband's intention to transition, despite Caitlyn maintaining she had told Kris about her desire to become a woman during their marriage.

The book also sensationally alleges that Caitlyn Jenner's very public transition and her Vanity Fair magazine cover were timed stategically to detract attention from her car accident which resulted in the death of one woman.

"Before Bruce got into the accident, he gave the world hints about his true sexuality," says a 'friend' of the Jenners. "After the accident, he went full steam ahead. I truly believe he was trying to misdirect the negative publicity he received after the car crash… it was clear he was worried about being charged."

This is the same book that claims Kris Jenner was behind the release of Kim Kardashian's sex tape, and that much of Keeping Up with the Kardashians is staged. NO! I never...
