The Met Gala is famously known as the Super Bowl of fashion. Why? Well, it's one of the most exclusive (and stylish) social events in the world, and celebrities always go all out for the occasion on the red carpet. Like the championship game, though, sometimes stars and their glam squads surprise Us with the unexpected - be it a never-before-seen hairstyle or a wildly unpredictable eye makeup. Take Nicole Richie, for example. She commanded attention with gray-white hair at the 2013 soirée to fit the event's "Punk: Chaos to Couture" theme.
