The charming Kristen Bell, who can be seen in this week's "Couples Retreat," has boarded Steve Antin's upcoming musical "Burlesque," which also stars Christina Aguilera, Cher and Stanley Tucci.

Aguilera plays a small-town girl who finds love and success in a Los Angeles neo-burlesque club. The Hollywood Reporter says Bell plays the club's lead dancer who gets mad when Aguilera steals her spotlight.

Bell heating up the big screen with some sexy dancing and stuff? Hey, I'm all for it. Cher plays the owner of the club, while Tucci plays the dude mentoring Aguilera's character. The film should be ready this time in 2010.

Besides "Couples Retreat," Bell will also soon star in "When in Rome." Her recent credits include the hilarious comedy "Forgetting Sarah Marshall," "Heroes" and, of course, "Veronica Mars."
