Charlize Theron Pictures in Red Lanvin Dress at 2012 MTV Movie Awards

Charlize Theron went with a red strapless 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 in the US and is released here on June 21. It faced stiff competition at the US box office from reigning champ Men in Black 3, as well as The Avengers. Nonetheless, Snow White and the Huntsman took the number one spot. Charlize has another big reason to celebrate — she may have another hit on her hands with her next movie, Prometheus, as well.
