Check Out Dakota Fanning's New 'Do

Dakota Fanning's got a brand new 'do!

The 18-year-old actress debuted her new hair color at Monday's premiere of The Twilight Saga: Breaking Dawn — Part 2. The natural blonde dyed her hair brunette for an upcoming role.

"I decided I needed a change," she told Yahoo. "For the character I was playing, I couldn't be a blonde."

In the final installment of the Twilight franchise, Fanning's character Jane and the Volturi will go head-to-head with the Cullen clan — and being evil has been a blast for Fanning. "It's nice to let go and know that your character is mean, and just have fun with it," she said. "It's good to be bad."

What do you think of Fanning's new hair color? Here's hoping blondes don't really have more fun.
