You get a pixie cut, and everything changes. At a launch party in Paris last night, Emma Watson revealed her new ad for Midnight Rose, the latest fragrance from Lancôme Trésor. Channeling Edie Sedgwick, the doe-eyed actress looks dashingly vintage.

Rumors started swirling back in March that the "Harry Potter" star would be the fresh face of Lancôme Trésor., and last night's soiree confirmed everyone's suspicions. Watson, who has modeled for Burberry and is in talks with Alberta Ferretti about collaborating on an eco-chic clothing line, is building an impressive resume with her blockbuster movies and flawless product campaigns.

We can't help but remember her as a frizzy-haired tween wizard, but we're starting to realize that with her new haircut and career ambitions, anything is possible.

Photographer Mario Testino, who shot the ad, agrees. He explained to Style.com that working with the 21-year-old student has been easy throughout the years.

"I've watched Emma grow up. She was a little girl when I first worked with her, then I shot her for Burberry, then British Vogue, then Lancome. The great thing about Emma is that she's a chameleon; she can communicate anything you ask."

The Trésor. scent, which has notes of Turkish rose and fruity-florals, is light and easy to wear, says Emma.
