Formerly a featured member of the Rapid Downsize club currently bowing down to newly slim star Colin Farrell, Matt Damon has notably chunked up for his role in the true story of an FBI whistleblower in Steven Soderbergh's The Informant. And despite the part's fun-filled requirements that he stop going to the gym and live on sweet potato pancakes with crème fraîche, Damon is reportedly feeling more than a bit self-conscious about his new frame. While Ben Affleck has taken the opportunity to relive his glory days as a funny sidekick, lashing out at Damon by nailing one-liners like "the man has to buy two seats on an airplane!", chubby Matt is fearing the month of November, when People announces his successor as "Sexiest Man Alive."
