A lot has happened to Britney Spears in her 30 years on this earth, and as they say, it's written all over her face.  Some YouTube genius has managed to create a video that charts the evolution of the star by morphing pictures of her face from infancy to the present day.

In just over a minute, you see Britney morph from an innocent baby, to a pre-teen Mouseketeer, to a teen pop Lolita, to Mrs. Federline , to mother, to wasted Paris Hilton companion, to crazy-eyed bald woman, to mature pop star, to the future Mrs. Jason Trawick , and the results are fascinating, and just a little disturbing.  The overly-dramatic music in the background doesn't help -- why couldn't they have picked one of her songs?
