Patrick Dempsey waved to his French fans between appearances in Cannes, France yesterday. He dressed in a casual neutral colored suit for his morning appointments around town before changing into a formal tuxedo and joining his wife, Jillian, and an elite Hollywood crowd at the amfAR's Cinema Against AIDS Gala held in Antibes. This trip is just one of many to come for Patrick who stars opposite Shia LaBeouf in this Summer's blockbuster sequel Transformer: Dark of the Moon. Shia's already started making the promotional rounds and dropped by The Ellen DeGeneres Show last week to retell the story of an infamous bar fight. Transformer opens nationwide July 1, but first Patrick dealt with more small screen drama on last night's Grey's Anatomy season finale, which closed out another successful season for the hit series.
