Kudos to Ronda. It looks like she had a really good time.
In all seriousness, if all of us had someone like that blonde woman shouting how great we are with so much genuine excitement, creating an atmosphere of fun around us, even just a couple times a year, I think we'd all be happier in life.
I'm glad she got this opportunity. She needed a little joy.
I'm a big fan of bodypainting in general, and I don't at all mean in any kind of sexual way. It's such a cool thing to use your own body as a canvas for art, and so interesting that so much energy can be spent to create the art, only to have it washed away after a photoshoot or event.
If you'll be civil about it and not ask to see her tits and whatever, please check out KayPikeFashion on twitch (or instagram, or facebook, or wherever, but she live streams the paint process on twitch). She does primarily comic book characters, but I think there's enough of a crossover audience with MMA fans that there's gotta be a handful of you who would appreciate what she does. She explains everything as she goes, and the channel is super chill, so if you like what you see in her final images, check out a live stream sometime and come ask questions. I think you'll find yourself enjoying the art and the community.
edit: For all of you doing nothing but hating because you aren't sexually attracted to Ronda's body, you're sad. She doesn't exist so you can jack off. She's an athlete, and in this case, a piece of art. Enjoy it for what it is: art. Go find some porn or something if all you want is fap-material. Honestly, watch that video and try to tell me whether it looks like they're having fun, making art, and taking cool photos, or whether they are trying to make porn. It's pretty clear what is going on.
