Poor little Ashlee Simpson. She ran with the acid-reflux defense but left the deviated septum cover up for grabs. (Luckily, Jennifer Aniston is not one to look a gift horse in the mouth...or nose.) Still, none of the littlest Simpson's alleged modifications put her on par with Christina Aguilera, who may be trailing her blond pop comrade on the way out of Hyde but is more than leading the way where it counts.
