The Costume Institute Gala this year celebrated the opening of the Punk: Chaos to Couture exhibition at the Metropolitan Museum of Art.
And the stars didn't shy away from the punk theme. Although Sarah Jessica Parker and Madonna had to the punk queens, Miley Cyrus and Anne Hathaway were certainly the punk princesses with their spiky and bleached blonde hairdos.
As well as styling her hair in spikes, Miley Cyrus also donned a racy fishnet-style Marc Jacobs dress.
Anne, meanwhile, even dyed her hair bleach blonde and sexed up the theme in a sheer Valentino dress with feathered cuffs.
Who won the battle of the bleach babes?
