Transformation

In her Oscar-winning role in La Vie En Rose, Marion Cotillard perfectly embodied Edith Piaf, from her street-urchin beginnings to her ugly descent into drug addiction. Amazingly, the French star may have been more comfortable donning a bald cap then the retro curls she later sported at the Academy Awards. "I was afraid to look pretty when I was younger," she told InStyle. "I thought it was superficial. But now I know that feeling beautiful makes me more confident and that's a good thing." A good thing indeed.

The French star of A Very Long Engagement tucked her short blond crop to the side with a decorative bobby pin.
