Did you watch the finale of “Dancing With the Stars” last night? If you don’t know by now, the winner was announced and it wasn’t Bristol Palin or Kyle Massey. The tacky disco ball trophy went to dirty dancer Jennifer Grey and her professional partner Derek Hough. Now that that’s out of the way we can talk about the important stuff like Christina Aguilera’s big performance that promoted her feature film debut, Burlesque.

She sang the lead track off the film’s soundtrack entitled, “Show Me How You Burlesque” and her “DWTS” performance was similar to the one she gave at the American Music Awards earlier this week. Has this movie pushed Aguilera into a Pussycat doll phase that she can’t escape? The premise of Burlesque centers on a small town girl who gets mentored by a legendary singer and is molded to become the next big thing. And oh what a star that girl has become. Watch her shimmy below…

Burlesque opens in theaters everywhere on November 24 (today!).
