Melissa McCarthy hit the red carpet at tonight's MTV Movie Awards in LA. She's on hand tonight as a presenter of one of the evening's many golden popcorns.

Melissa stars in the film opposite Sandra Bullock, and we'll be able to see their buddy antics on the big screen starting June 27. What do you make of Melissa's red-carpet ensemble?
