Christina Aguilera to star in 'Burlesque'

Christina Aguilera has crammed a lot of living into her 28 short years on this planet.

From a childhood appearing on "Star Search" and "The Mickey Mouse Club," she went on to win four Grammy Awards, not to mention get married and give birth to her first child, Max Liron Bratman.

Plus, Aguilera has lent her famous face to Mercedes-Benz and Versace, among others, and her famous voice to an animated fish in "Shark Tale."

But believe it or not, despite her long and varied resume, Aguilera has never appeared on the big screen in the flesh. Until now, that is.

The songbird is set to make her big-screen debut in an upcoming musical called "Burlesque."
