Caitlyn Jenner’s memoir The Secrets Of My Life isn’t out until April 25, but thanks to a preview copy of the book obtained by Radar Online, some of Jenner’s revelations have already been made public.

The most explosive admission might be Caitlyn’s opinion on the OJ Simpson murder case, in which Kris Jenner’s former husband Robert Kardashian defended Simpson on charges of murdering his wife Nicole Brown and her friend Ron Goldman.

In the book, Jenner makes the revelation that the late Robert Kardashian told her before his death that he thought Simpson was guilty.

Caitlyn, back then known as Bruce, says Robert told her:

“I would’ve been okay with it if they had gotten him in the first trial.”

“The implication was obvious that he believed O.J. was guilty,” the-67-year-old wrote. “I believe [Simpson] got away with two savage murders.”

Simpson was found not guilty of all criminal charges in 1995, although he was deemed ‘responsible’ for their deaths in a civil lawsuit in 1998, and ordered to pay millions to both the victims’ families.

Jenner also shares the rather twisted view that lawyer Kardashian defended Simpson in order to get back at his ex Kris Jenner, who was close friends with Nicole until her murder.

“I wonder if it was his way of saying to her what I think she was saying to him when she married me: a big f*ck you,” Caitlyn wrote.

In The Secrets Of My Life, Jenner also confirms she underwent gender reassignment surgery in January, after coming out as transgender in 2015.

“I am going to live authentically for the first time in my life. I am going to have an enthusiasm for life that I have not had in 39 years since the Olympics, almost two thirds of my life.”

If you’ve got more questions for Caitlyn on that topic, good luck.

“You want to know, so now you know. Which is why this is the first time, and the last time, I will ever speak of it.”
