The other night on "Conan" Charlize Theron talked about her obsession with UFC, or as she put it, watching "sweaty, hot men bleeding all over each other and bashing each other in the face." So what's a delicate flower like Charlize doing watching such a brutal sport? Well, nothing out of the ordinary, apparently.
Sure, we already know about the athlete fans or the burly dudes who follow the sport, like Joe Rogan, Michael Clarke Duncan and Kevin James. But in just another sign of MMA's meteoric rise into the mainstream consciousness, there are plenty of wimpy, girly or frou-frou celebrities who love them some ass-kicking action.
