Kim Kardashian Breaks Down While Talking About Mom Kris Jenner & Bruce's Transition (Video)

Kendall and Kylie Jenner keep it low-key while leaving Nobu after having an early dinner on Saturday (May 16) in Malibu, Calif.

In a new clip from Bruce Jenner‘s upcoming special, the girls sit down with their sister Kim Kardashian to talk about their mom Kris and dad Bruce‘s transition.

“He’s gonna tell his full story, at first I was like I was ‘I’m totally gonna cry, I’m totally gonna cry,’” Kim tells Kendall and Kylie. “I was thinking, ‘Mom this is really hard for her.’ It’s so sad. She cries all the time and it makes me really sad. We should really appreciate all the things she does for us, because she does a lot.”
