In what will be her first movie star role in a decade, Cher is set to join Christina Aguilera in “Burlesque,” a contemporary musical for Screen Gems.

Steven Antin will direct from a script he wrote that was revised by Susannah Grant (Daily Variety, May 4).

Aguilera will play an ambitious small-town Iowa girl with a big voice who comes of age in a neo-burlesque club on Sunset Boulevard that’s run by Tess (Cher), a former dancer who struggles to keep the club open and gives the young girl a chance to shine.

Cher will sing onscreen. While her voice has been heard in many films, “Burlesque” will mark the first time she’ll be seen singing in a film she stars in. Cher last starred in “Tea With Mussolini” in 1999
