The soundtrack to the film Burlesque, starring Christina Aguilera and Cher, features new recordings performed and co-written by five time Grammy winner Christina Aguilera, with production by Tricky Stewart, Linda Perry and Ron Fair and songwriting by Claude Kelly, Tricky Stewart and Sia. The soundtrack also features two brand new tracks performed by the legendary Cher, including "You Haven't Seen The Last Of Me", a powerful Diane Warren-penned ballad which was produced by Matt Serletic. This marks Cher's first new original song in seven years as well as her first movie musical. The soundtrack also includes remakes of classic songs such as Etta James' "Something's Got A Hold On Me" and "Tough Lover" and Mae West's "A Guy What Takes His Time" all performed by Christina Aguilera. Christina Aguilera makes her theatrical film and musical debut as the lead character in Burlesque where she co-stars along with the legendary Cher in her first major film role since 1999.
