Charlize Theron went with a red Lanvin number for this evening's MTV Movie Awards in LA. She's fresh off a global promotional tour for Snow White and the Huntsman, which came out Friday. It faced stiff competition at the box office from reigning champ Men in Black 3, as well as The Avengers. Nonetheless, Snow White and the Huntsman is No. 1 at the weekend box office! Charlize has a big reason to celebrate. She may have another hit on her hands with her next movie, Prometheus, as well.
