She let her daughters take center stage in Caitlyn Jenner's support squad at Wednesday, July 15's ESPYS 2105 Awards — but although Kris Jenner wasn't there at L.A.'s Microsoft Theater for her former sopuse's big night, the Kardashian matriarch tuned in to check out Caitlyn's landmark speech.

Talking exclusively to Us Weekly about Caitlyn's big moment accepting her Arthur Ashe Courage Award, the momager was totally supportive of her ex's heartfelt speech.

"I think it was amazing and very brave," Kris, 59, told Us during Thursday, July 16's Amazon Summer Soiree at Los Angeles' Sunset Tower. "I think she looked beautiful," she added, of Caitlyn's jaw-dropping appearance in a floor-length cream Versace gown.

Jenner was joined at last night's Amazon bash by daughter Kendall Jenner, 19, who had watched her dad's speech from the front of the ESPYS' audience, along with all of her other siblings and half siblings, apart from step-brother Rob Kardashian who shied away from the very public event.

Kris revealed that their Thursday night mother-daughter hang out was very last minute, but says she and her children like it that way.

"I love being with my kids," Kris told Us. "I was on my way here to support the girls, the Foster girls, and I called Kendall and said, 'Get over here, let's go there for a minute and I'll take you to dinner.' That's the way it goes in my family, it's always spontaneous," she added.
