Caitlyn Jenner has made her fair share of headlines since joining the 21st century - from her debut, to her upsetting political views and most recently, the publication of her memoir, The Secrets of My Life.
It's no secret however, that Caitlyn's memoir ruffled more than a few Kardashian feathers as she not only had unsavoury things to say about ex-wife, Kris - Kim recently confessed there is a "2% chance of Kris speaking to Caitlyn ever again" - but also the late Robert Kardashian senior.
Caitlyn made it very public that she disliked O.J. Simpson, a former close friend of the Kardashian family. Simpson was made famous in the 1990's for being trialled for the murder of his ex-wife and her then lover. Kardashian Senior grew to fame as one of the lawyers on Simpson's defence team.

During a coming episode of Keeping Up With The Kardashians, Kim reveals that Caitlyn wrote, "Robert Kardashian knew O.J. Simpson was guilty but joined the defense team to get back at his remarried ex...Robert told Caitlyn in secret after the O.J. murder trial that he believed his friend was guilty.
Khloe, Kim and Kourtney, all daughters of Kardashian Senior, were shocked at the claims calling them flat out lies. "Dad so believed [O.J.]. It is so shady that Caitlyn came over, gave me the book and then on the phone said, ‘Well, the final version has a few more things in it. But don't worry, it's nothing about you.' She lied to me because that is about me if it's about our dad."
Kim expressed her distain for Caitlyn's actions and general disappointment as she said, "I have always had Caitlyn's back. She is a liar. She is not a good person."
Looks like the season of Keeping Up is going to be as juicy as ever. Check out the full clip here.
