Here is a short inside bit on story of Burlesque.
Christina Aguiliera makes her dramatic feature debut as Ali, a small town singer who takes her shot at stardom performing at a neo-burlesque nightclub in Los Angeles. Situated in a regal old theater that's still dazzling despite having fallen into disrepair. The Burlesque Lounge is the kind of club where legends are born. When club owner Tess (Cher) hires charasmatic Ali as a cocktail waitress, the ambitous big-city newcomer goes to great lengths to make a good impression. Taken under the wing of a friendly featured dancer (Julianne Hough). Ali quickly realizes that not everyone is quite as nice when she forms a friendship with bartender/aspiring musician Jack (Cam Gigandet) and incurs the wrath of the club's cattiest showgirl (Kristen Bell). After making her leap to the stage with a little help from a sympathetic stage manager (Stanley Tucci) and the club's playfully adrogynous host (Alan Cumming). Ali becomes the star attraction at the Bulesque Lounge and the crowds start packing in. Later, a wealthy businessman (Eric Dane) makes a bid for the club while to trying to charm the talented young performer straight into his arms.
