It stars Cher, Christina Aguilera, Kristen Bell, Cam Gigandet, Stanley Tucci, Julianne Hough, Alan Cumming, and Peter Gallagher, and features cameos from Dianna Agron, and James Brolin. The film tells the story of Ali (Aguilera), an aspiring singer who leaves her small hometown for Los Angeles, where she becomes a dancer at a struggling burlesque lounge owned by Tess (Cher). After a performance is sabotaged by her rival, Nikki (Bell), Ali sings the song herself, impressing Tess and leading to her becoming the main attraction of the lounge. Burlesque marks Aguilera's first leading role, as well as Cher's first musical performance on screen since 1967's Good Times.
