Lady GaGa slipped a nipple

Lady GaGa’s nipple popped out at a recent signing. It was alright. Sort of like finding out your bike has 11 speeds instead of 10. I give this a 5/10 on the nipple slip scale. 1 for clarity of the nipple plus 4 for being, I hope, on a chick. Click through the header to see the NSFW pic.
