Where You've Seen Her: Besides being our September 2013 cover girl, the gorgeous Ronda Rousey is best known for being the current UFC Women's Bantamweight Champion, a title which she managed to maintain even after her Saturday night fight against Sara McMann. A total knockout in both the ring and the looks department, this California babe also snagged #29 on our 2013 Hot 100. Now you can catch her sitting down with comedian Pete Holmes on his late-night talk show February 25 on TBS. Get ready for a good laugh and a good sweat.
