"I would love to be there to support my father," Brody told ET of Caitlyn's big night. "It'd be a great thing. ...I'll be there to support Caitlyn 100 percent."
It certainly isn't lost on the 31-year-old reality star on what a honor this is for the 65-year-old former Olympian. "It's a huge deal. Absolutely. I'm always there to support Caitlyn," he said while at Tuesday's Spy Chatter App launch event at The Argyle in Hollywood. "There's a lot -- a lot of moving parts. I'll just say that. We do have a big family."
Brody gushed over how Caitlyn's journey has brought the whole Jenner/Kardashian brood together.
"It's been incredible," he said. "I'm not going to sit here and say it's been the easiest thing in the world but it helped me in a lot of ways. It helped the family in a lot of ways just to be incredibly open."
Brody adds that his family has "absolutely" never been happier. "You look at somebody and you don't really know what they're going through. And that's anybody, not just my father, but a lot of other people out there in this world," he said. "The one thing that you want for them is for them to be themselves and for them to be comfortable in their own skin."

Praising Caitlyn, Brody continued, "And finally, Caitlyn has been able to do that and it's a beautiful thing to see and I think everybody should go through life -- because it is very short -- being the person that they truly are and who they want to be."
