Caitlyn Jenner has done a 'tell-all' interview with Piers Morgan, in which she explained the process of writing her book The Secrets of My Life.
It appears that there were some parts she didn't reveal to the Kardashians before it went to print, due to the fact she didn't trust them.
Caitlyn told Piers that when it came to her gender reassignment surgery, she didn't tell the family because she didn't trust Kim and Kris in particular.
She revealed to Piers when she sent a copy of the book to Kim before publication, it didn't include the last few pages where she discussed her transition.
When asked if they knew did she have surgery, Caitlyn replied 'No, I didn't tell anybody. Why? It's none of their business. No, it's not that big a deal. Nobody knows. I had to be honest, the book is about honesty. It's called The Secrets of My Life. I had already been living as Caitlyn for a year and a half, OK, nobody knows anything.'
She added that she didn't trust them to not leak it to the press and said 'I hate to inform the Kardashians that the book was not about them.'
Caitlyn also confirmed that she talks to Kendall and Kylie everyday, but her relationship with Kris and the Kardashians has faded.
