In Keeping Up with the Kardashians: About Bruce, which airs tonight and tomorrow on E!, Kim Kardashian reveals that it took her mother Kris Jenner quite a long time to adjust to her ex-husband's revelation that he's transitioning.
"This is really hard for her," Kardashian says of her mother in a sneak peek from About Bruce.
In the clip, which was taped before Bruce Jenner's interview with Diane Sawyer aired on 20/20, Kardashian tells her sisters: "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."
Kris Jenner publicly voiced her support for Bruce after the 20/20 interview aired.
Not only was I able to call him my husband for 25 years and father of my children, I am now able to call him my hero.— Kris Jenner (@KrisJenner) April 25, 2015
