Circling the Pool

Ooh, Kristen Bell – you naughty.

The actress is going to star in The Lifeguard, the story of an almost-30 New York City reporter who leaves it all behind to go back home, takes back her job as a high school lifeguard, and starts a dangerous dalliance with a 16-year-old.

Mmm...so...not a comedy?

Up next for Bell is a laugher, though: Hit & Run, the one by her bf Dax Shepard.
