In a sneak peak of Sunday's "Keeping Up with the Kardashians," the gold medal-winning Olympian stopped by the home the former couple used to share to bring Kris a copy of her new memoir, "The Secrets of My Life."
The subject of gender confirmation surgery comes up after Caitlyn inquired about retrieving the gun she left behind when she moved out.
"The only problem that I have with the gun is it's registered in my old name," she told Kris. "I've got to get that changed. I've got everything changed, but in some states, I think if you go through gender confirmation surgery, it's the only way you can ..." she continues, trailing off.
Caitlyn is set to release her memoir "Secrets of my Life" on Apr. 25th. A few excerpts from the book have already been released, and the Kardashian-Jenner clan is apparently less than pleased.
"I really tried hard to improve the relationship and spend a little bit of time, thinking maybe there's something here that I'm not seeing," Kris said. "I've done nothing but open up my home and my heart to a person who doesn't give a shit. So, I'm done."
"I've never been so angry and disappointed in somebody in my whole life."
"Keeping Up with the Kardashians" airs Sunday nights on E!
