Letterman Tastes Jennifer Lopez's Perfume (VIDEO)

Jennifer Lopez was on Letterman last night to promote her upcoming film (probably some subtle, art-house flick). But never mind that - the highlight of the interview came when Dave sprayed her perfume in his mouth. And not just a quick spray for shock value. A healthy dose - spray after spray. Easily the most entertained we've been by a J-Lo interview.
