Hair flashback!

Emma Watson has returned to her roots, the faux way, for her upcoming flick The Bling Ring.

VOTE: Which celebrity has the best hair in Hollywood?

On the set of the new Sofia Coppola-directed film, the 21-year-old Brit was spotted sporting a wig of long brown hair, reminiscent of her Hermione Granger mane in Harry Potter.

Watson made headlines in 2010 when she chopped off her long brown hair into a punky pixie cut -- a style that is requested so much at hair salons, it has since outnumbered the demand for another famous mane: Jennifer Aniston's.

"I knew it would be kind of a shock, but I had no idea that it would be that big," the stylish star told USA Today a month after she lopped off her locks. "Like everyone would make this much fuss over it."
