Amy Adams

Thanks to the 2007 box office hit Enchanted, audiences are well aware of Amy Adams' vocal talents. But who knew  she could also rock a poodle skirt and a high ponytail so well?

When Adams appeared on Late Night with Jimmy Fallon Monday to promote her new movie American Hustle, Fallon revealed he had found an old commercial of the Oscar-nominated actress singing in a Grease parody for a bank. "That's my first on-camera job," a shocked Adams tells Fallon, adding that she's never seen the ad before.
