Snow White and the Huntsman star Charlize Theron was spotted ringside at the Ultimate Fighting Championship 146 at the MGM Grand in Las Vegas Saturday. The actress, in a sleek black ensemble, looked on as mixed martial arts fighter Junior Dos Santos took down Frank Mir in a bloody battle.
Earlier in the day, the new mom enjoyed a quieter activity: dinner with five friends at Spago restaurant. The group dined on an array of items, including crab cakes, prosciutto pizza and tuna sashimi. Theron was in Sin City to celebrate a friend’s birthday before continuing on her Snow White press tour.
