Michelle Waterson, with all due respect to Ronda Rousey, might be the sexiest current female mixed martial artist in the world. How do I know this? This hot new bikini video featuring Waterson in a bikini is a good indication.Unfortunately Michelle Waterson isn’t heavy enough to fight in Rousey’s weight class so the dream matchup of all dream matchups (Gina Carano aside) can’t happen. Waterson is just a tiny thing at 5’4″ and around 105 pounds. According to FightMatrix, Waterson is currently the #1-ranked female atomweight (106 lbs) fighter in the world, meaning not only does she look damn fine in a bikini she’s also capable of beating some serious ass. I like her.
