Not so "dirrty" after all

Gotta say I'm loving this pic of a stripped down Christina Aguilera:

I didn't even recognize her at first. But wow - she looks beautiful. Must be nice to look better without makeup. I wouldn't know anything about that.

And then there's this photo of Britney Spears:

I didn't even recognize her at first. Or at second. Or still. I swear to god this isn't her. And if it is, they photoshopped the hell out of her. Again, I wouldn't know anything about that.
