Christina Aguilera Says Her AMA Performance Will Be A ‘Spectacle’

'You're going to get quite the show,' she tells MTV News of performing a 'Burlesque' number at Sunday's show.

The American Music Awards are known for their high-octane performances , and this year is no exception, with Taylor Swift, Miley Cyrus, Kid Rock, Justin Bieber, Katy Perry, Ke$ha, Pink, Usher, Ne-Yo, Diddy and more set to hit the stage.

Christina Aguilera will also be performing, doing a number from her upcoming movie “Burlesque.” When MTV News caught up with the Grammy winner/ movie newbie recently, while doing press with her hunky “Burlesque” co-star Cam Gigandet, we asked her what fans can expect from her AMA performance.

“It’s going to be fantastic,” she said. “And it will give you a fitting little look inside the movie.”

Aguilera said her saucy, burlesque-style dancing will set her performance apart from past appearances.

“It will be another very new challenge for me,” Aguilera admitted. “My legs have been incredibly sore as I stepped into the role of Ali for this.” In the film, Aguilera plays a small-town girl with big dreams — Ali — who stumbles on a burlesque club owned by the feisty Tess (Cher).

Aguilera added that, while re-learning the dance routines was grueling, the choreography is amazing. “You’re going to get quite the show,” she promised. “Quite the spectacle.”

While Aguilera is new to the world of acting, Cher told MTV News that the pop star can dish it out with the best of them. “The scenes that she and I had together, I really enjoyed, and I really believe that she’s got definite chops,” she said. “We worked well together. I enjoyed all of it, and she was toe-to-toe with me the whole time.”
