Actor Jason Segel showed off a svelte new look in Boston, Massachusetts on Wednesday (16Oct13) as he stepped out during a break in filming new comedy Sex Tape. The Forgetting Sarah Marshall star, who previously touted a chubby frame, was noticeably slimmer after spending his summer (13) getting into shape for the raunchy role, in which he and Cameron Diaz play a married couple sent into a panic as it tries to track down a missing sex tape.
