Kristen Bell dances through pain for new 'Burlesque' movie role

Kristen Bell is getting neck pain and soreness in her inner thighs from a workout set to prep her for an upcoming movie role.

"I've started dance rehearsals and my neck is sore and my inner thighs are so sore," 29-year-old Bell told E! Online at the Vanity Fair-hosted launch of Guess?'s new T-shirt benefiting Invisible Children.

E! debunked rumors that her training is for the hit TV series Dancing with the Stars, but confirmed Bell is working up a sweat in which Bell and Christina Aguilera will costar as dancing rivals at a Hollywood Burlesque club. 

The flick is also set to feature Cher, Twilight hottie Cam Gigandet, Julianne Hough and Stanley Tucci.

The sexy Kristen Bell will have to keep up with her current fitness regime to bare skinny outfits fit for a Burlesque star.

"My character is fun and sexy but not a stripper," Bell told E!. "There is no nudity, and there are no pasties and G-strings."

According to the report, Bell's costumes will run along the lines of "Madonna-esque cone bras" and "Marilyn Monroe boy shorts—the high-waisted panties kind of thing," Bell explained.
"Burlesque is a tease. It's not meant to really give that much away because that wouldn't be considered a tease. It would be considered giving away the goods."
