Kris Jenner might not have been sitting in the audience at the 2015 ESPY Awards, but you better believe she tuned in to see Caitlyn Jenner accept the Arthur Ashe Courage Award!

The Keeping Up With the Kardashians star was extremely proud of her ex, telling Us Weekly she thought Caitlyn's moving speech "was amazing and very brave."

The famous momager, 59, raved about the way Caitlyn, 65, looked in her Angelia Jolie-inspired white Versace gown, too, saying simply, "I think she looked beautiful."

Kris, of course, isn't the only family member praising Caitlyn for using her platform to make a difference in the transgender community. All six of the Olympian's biological children (Kylie, Kendall, Brody, Brandon, Casey and Burt Jenner) attended the awards Thursday in support of their father, and three of Caitlyn's stepchildren (Kim, Khloé and Kourtney Kardashian) watched proudly from the audience as well.

Caitlyn had to fight back tears as she thanked her family during her acceptance speech. "I never wanted to hurt anyone else, most of all, my family and my kids. I always wanted my children to be so proud of their dad for what he was able to accomplish in his life," she said. "You guys have given so much back to me, you've given me so much support. I am so, so grateful to have all of you in my life. Thank you."

After the ESPYs, she admitted to Good Morning America's Robin Roberts that "it wasn't easy" to hold her emotions together when talking about her kids onstage!

"My family have been so supportive of what's happening," Caitlyn gushed. "My kids are great. They're absolutely wonderful. I'm blessed to have just wonderful children."
