Kirsten Bell “Couple Retreat” Cutie

She’s been hard at work on her latest movie “Couples Retreat” and from the looks of it,  Kristen Bell will be steaming up the silver screen in plenty of bikini action.

New photos of the “Forgetting Sarah Marshall” hottie have surfaced from the set of the new flick, and she looks amazing in her sexy little two-piece.

And it sounds like “Couples Retreat” will be more than just a treat for the eyes, as the film boasts a killer ensemble cast.

Stars like Malin Ackerman, Jason Bateman, Kristin Davis, John Favreau, and Vince Vaughn all star in the movie, due in theaters on October 9th.
