Everyone saw Ronda Rousey get knocked the eff out on Saturday, right? Quite the upset, that was. Regardless of how rough the Octagon can be, we've mostly got our eyes on what goes on between rounds. We'd love to go full contact with UFC ring girls like Brittney Palmer, Arianny Celeste, Amber Nichole Miller and Jessica Cambensy. We're pretty sure they're responsible for at least half of UFC's pay-per-view buys.
