You know, I walk down the street all the time, and while I pass some very good looking women, not one of them has ever had a nipple pop out of her shirt, let alone a whole breast. So how do moments like these Lily Allen nipple slip pictures keep happening to all these celebrities? Could it be that they're doing it on purpose?
