Having really slimmed down over the past month, Christina Aguilera strutted her stuff on set of “Burlesque” in Los Angeles on Tuesday (November 17).

The “Genie In a Bottle” babe is hoping to impress in her new role - as she was cast along with some heavy hitters in the song and dance community for the musical drama.

Due out in November of 2010, “Burlesque” will be directed by Steve Antin, with Christina’s co-stars including Kristen Bell, Cam Gigandet, Cher and Julianne Hough.

A synopsis via IMDB tells of the plot: “A small-town girl ventures to Los Angeles and finds her place in a neo-burlesque club run by a former dancer.”
