Kristen Bell has crossed over to the dark side! In the upcoming movie musical Burlesque, co-starring Christina Aguilera and Cher, Bell covered up her blond locks and summoned her inner vixen. "When I had the wig on I didn’t even recognize myself in the mirror. I felt like another person," the actress told us of playing Nikki, a jealous dancer plotting to destroy her biggest rival, played by Aguilera. "Now I'm over being blond. If I’m well received as a brunette in Burlesque then maybe I'll go brunette [in real life]!" While the actress says her movie makeover (which also includes barely-there costumes and some sultry moves she picked up during three months of dance training) helped her get into character, she denies that there were any real divas on the set. "In most of the scenes Christina and I had together we're bitchy to each other, but it was hard for us to keep a straight face," she said. "We got along so well that it was hard for me to be mean to her!" Click through our gallery for more photos from the film and watch the trailer after the jump!
