Bye, bye brunette!

Emily Blunt debuted a new look at the red carpet premiere of her new film, Gnomeo & Juliet, in Hollywood on Sunday. Her normally chocolate-brown locks were lightened to a sweet shade of strawberry blonde.

The hair switch-up stays true to Blunt's self-described "schizophrenic" style. "I'm kind of effectively bipolar!" she told at the premiere.

The shade is the latest step in the gradual lightening of her dark hair for her role in the upcoming thriller Looper, according to StyleList. The actress, who married John Krasinski in July, has been reportedly visiting colorist Anival Morales weekly for a more natural change.
