The number one movie in the nation, The Hangover, has taken its cast oversees for a bevy of international premieres. Heather Graham joined her male castmates Bradley Cooper, Ed Helms, Justin Bartha, and Zack Galifiankis on the red carpet yesterday to premiere their hit movie in London. Wearing a blue Michelle Jonas dress, with some strategically placed cutouts, Graham stole the attention from the boys and reminded us why we've been missing her on the red carpet the past few years.

If you have yet to see The Hangover, make it your number one priority this weekend, it's one of the funniest movies we've seen all year.
