Caitlyn Jenner has said that she did not tell her fellow Kardashian clan about her gender surgery as it was “none of their business.”

Jenner had concealed her reassignment surgery because she did not trust her family not to go to the press, she has admitted.

Speaking on Piers Morgan's Life Stories, Jenner said when she sent a copy of her memoir The Secrets Of My Life to Kim before publication, it did not include the last few pages in which she "talked about gender confirmation".

The 68-year-old said: “I didn't tell anybody. Why? It's none of their business."

“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."

Asked by Morgan if specifically keeping the revealing portion of the book away from the Kardashians was "wilfully deceptive", Jenner said: "Because I didn't want them to leak it to the press. And there was no reason for them to know about it."

She added: "Of course I didn't trust them, yeah. I hate to inform the Kardashians that the book was not about them.”

The former Olympic champion, previously married to the family's matriarch Kris Jenner, has also said she is no longer in contact with stepchildren Kim, Khloe, Kourtney and Rob Kardashian.

The TV personality revealed that they just “don’t communicate like we used to”.

"It's not even a problem, I just don't communicate with them like I used to," she said.

"Well, it hurts but it's not the end of the world. Fortunately I have a lot of children."

Jenner, who has six biological children from three marriages, said: "Yeah, I really don't talk to them anymore.

The media mogul, who first came out as a trans woman nearly three years ago, said that her two children with Kris, Kendall and Kylie, speak to her "all the time, every day".

"The only ones I'm really concerned about are Kendall and Kylie, yeah they are biological kids. Although the Kardashians, I spent 23 years of my life carpooling those kids around, raising them, taking care of them."

Piers Morgan's Life Stories: Caitlyn Jenner airs on Thursday at 9pm on ITV.
