Caitlyn Jenner says she didn't "trust" the Kardashians enough to share her gender confirmation surgery plans.
"I didn't tell anybody. Why? It's none of their business," Jenner told host Piers Morgans.
"It really wasn't that big of a deal. I went to the hospital, no big deal. I'd already been living as Caitlyn for a year and a half."
"I didn't want them to leak it to the press, OK? And there was no reason for them to know about it," she added before confirming she didn't trust the Kardashians, "Of course not -- of course I didn't trust them."
Jenner confirmed she's transgender in April 2015 after splitting from Kris in September 2014 following nearly 23 years of marriage.She underwent gender confirmation surgery in January 2017, which she detailed in her memoir, Secrets of My Life.
"I don't talk to the Kardashians anymore," the star said of Kris' children Kourtney Kardashian, Kim Kardashian, Khloe Kardashian and Rob Kardashian.
Jenner spent time with Kendall, her elder daughter with Kris, on Thursday.
She shared a photo with the 22-year-old model on Instagram, writing, "My girl loves her horses!"
