As the Keeping Up with the Kardashians special on Bruce Jenner’s transition approaches, we've seen Khloe present him with gifts, Kris express her support, and now in this new preview clip from About Bruce, a proud and emotional Kim breaks down in tears while talking with sisters Kendall and Kylie about appreciating their mother. Chatting about Bruce's decision to be interviewed by Diane Sawyer, Kim tells her sisters that "At first I was like, 'I'm totally going to cry! I'm totally going to cry!' My throat was literally burning." Then, on matriarch Kris Jenner, "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."
And in this heartwarming sneak peek, vintage family home movies air as voiceover of the Kardashian and Jenner daughters praising their father plays. Family support is invaluable.
