Mixed martial arts (MMA), she is a cruel mistress.

Cerrone, who is fresh off a UFC Fight Night 45 win over Jim Miller earlier this week in Atlantic City, New Jersey (watch it), is expected to remain on the "Sin City" card; however, it will not be in a rematch against Nate Diaz, a fight UFC President Dana White called "ridiculous."
