The sisters were both seen wiping their eyes as the 65-year-old former Olympian called attention to how understanding his family has been during his transition.

"I'd like to thank my family. The biggest fear of coming out if I never wanted to hurt anyone else. Most of all my family and my kids," Jenner said. "I always wanted my kids to be proud of their dad for what he was able to accomplish in his life. You guys have given so much back to me, you give me so much support. I am so, so grateful to have all of you in my life. Thank you."
