This is Soviet-born Peruvian MMA fighter Valentina Shevchenko.
She has been a kickboxing and muay thai champion, and is currently one of the top fighters in the UFC. She has beaten most of the top fighters in the 135 pound division, which is impressive because she is quite a bit smaller than they are. Some of them cut 20 or more pounds to make the 135 pound limit, while Shevchenko doesn't cut any weight. She came within a razor-thin split decision of winning the 135 pound title. Now that UFC has a 125 pound women's division, she gets to fight women her own size, which she did last night for the first time in UFC. Her opponent landed one punch, Valentina landed somewhere over 200 punches, and it was a terrible mismatch. It was extremely bloody and rather gross. Shevchenko was so splattered with her opponent's blood that she looked like a Jackson Pollock painting. They needed a squeegee and a bucket to remove her opponent from the ring. The referee should have stopped it much sooner. The Brazilian girl's corner should have thrown in the towel. The UFC should have never set up this fight in the first place.
Anyway, after all her wins Valentina does an amusing victory dance, which I was trying to find a video of. Instead...
...here's ruthless killer Valentina Shevchenko dressed up in a "Naughty Firefighter" costume competing in some kind of dance competition on Peruvian TV.
