Jenner claims in the book The Secrets of My Life obtained by RadarOnline, that one day she and Kardashian were in a car together a few years after the trial and he said: "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," Jenner concludes.
She says she banned Simpson's named being mentioned in the house after Kourtney reportedly said "see, I told you he didn't do it", after Jenner picked her up from school the day of the not guilty verdict.
Jenner said he had never been impressed by Simpson, even before hooking up with Kris.
"He was the most narcissistic, egocentric, neediest a**hole in the world of sports I had ever seen, and I had seen a lot of them," she said. "I believe he got away with two savage murders."

Jenner says she believes that part of the reason Kardashian agreed to represent Simpson was as pay back to his ex-wife for their 1991 divorce.
"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*** you," he said.
In her book, Jenner also reveals that she has started genital surgery, two years after the Olympic-winning decathlete announced she had transitioned to a woman.
"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," Jenner wrote.
