Lady GaGa's outfit fails to contain nipple. GASP!

This was bound to happen: Seen here with Bobby Brown circa 1985, Lady GaGa slipped a nip while signing autographs in Portland, Oregon last night, and based on her outfits, is anybody really surprised by this? It's sort of like finding out Britney Spears had a secret third son but traded him for some Oreos at lunch. Ooh, shocking.

NOTE: Pic links to NSFW version that's really not worth getting fired over. I'm man enough to admit that. Ladies?
