Kristen Bell attended the premiere of The Hangover at El Capitan Theater in Los Angeles last night.

The comedy starring Bradley Cooper, Ed Helms, and Zach Galifianakis is about 3 friends who go to Vegas to celebrate their friends impending nuptials and get so drunk in the process that they lose the groom-to-be and their memory of the previous nights events. They must retrace their steps in order to find out where their friend is.

The Hangover hits theaters this Friday
