Marion Cotillard became famous for her chameleon-like turn as Edith Piaf in "La Vie en Rose," but the actress makes a hobby out of transforming her own image off-camera, too. Especially with her various hairstyles.

Most often seen wearing her hair in beautiful, ribbon-like curls, Cotillard stepped out at the London premiere for "Public Enemies" last night (June 29) with poker-straight hair, the top half styled into a formidable pompadour. (There was a slight mullet thing going on as well -- a hair stunt only a Dior muse/Oscar-winning actress could pull off.)

Cotillard's so gorgeous, she could make a buzz cut look chic, but there is something about her curly hair that just makes her seem that much more glamorous and mysterious (to me, anyway).
