4. MICHELLE LARCHER DE BRITO

De Brito said about her grunting, which got her booed off the court at the 2009 French Open, that no one can tell her to stop and that she won't do something that will change her game in any way. Recently, though, the defiant pro did say, "I'm still learning. Maybe I can eventually put it under control. I don’t know, but I’ll try." We can't be the only ones who disagree with this, right? Grunt, moan, do whatever you have to in order to win and make the sport that much sexier—it's all good.
