Christina Aguilera is "fascinated" with burlesque.

The 'Dirrty' hitmaker is fascinated by showgirls and Cabaret and was delighted to be offered a role in the movie 'Burlesque' as it encompassed her passion.

She said: "There have been a lot of roles and scripts that have come my way but nothing that really inspired me or intrigued me like when 'Burlesque' showed up at my door. Just the whole concept of burlesque, I've always been fascinated with it.

"I've always collected so many books about burlesque. I've been intrigued by the time that it's set in, in the 20s, 30s, 40s and so I knew it was a no brainer for me to be a part of once I met with the team."

Despite the theatrical nature of many of her music videos, Christina insists that shooting visual accompaniments to her singles didn't prepare her for working on a movie set.

Asked if her videos helped with preparing for the film, she said: "No, it doesn't actually. Yes, I've been around the block with it before but doing a movie and doing this kind of a movie is a whole different animal. I completely had to throw away everything I knew about anything and approach doing this movie with an open heart, being truly vulnerable, truly naive as my character is, and open myself up as a newcomer in a whole new way for everything that I did on this movie."
