What is it with ladies sporting Barbie-esque makeup on Letterman? First there was Heidi Montag, and now Paris Hilton. Yesterday afternoon, the meticulously groomed socialite arrived to the set of the show with glowy, tan makeup and hair that hangs lower on the left side only. We know that it's an extension, and she must love it since she draws attention to it with that one twisty curl, but it just looks odd and off-balance to me (even though I know that's the idea). What do you think of this hairstyle?
