Kristen Bell sports a swimsuit in Forgetting Sarah Marshall, where she stars with Jason Segel, Bill Hader, Jonah Hill, and Paul Rudd.  Devastated Peter (played by Segel) takes a Hawaii vacation in order to deal with recent break-up with his TV star girlfriend, Sarah (that’s Kristen). Little does Peter know Sarah’s traveling to the same resort… and she’s bringing along her new boyfriend.
