Spitting in the face of the old "blonds have more fun" theory, AnnaLynne McCord has ditched her signature blond hair for a darker 'do. Don't fret if you're a fan of her golden locks—the brown shade comes courtesy of colored mousse used to darken her hair for a film project, her agent told us. (Possibly "Officer Down" opposite David Boreanaz, if IMDb is any indication).

Rest assured, AnnaLynne's new look doesn't mean she's changing zip codes (or at least not fictional ones).

"'Okay! I'm NOT leaving 902 and the hair is for a movie I'm shooting right now. I adore all of you!! Xxx," she tweeted in response to worry from fans.

The "90210" star may have changed looks for a role, but we're digging the new style. Going blond for the summer is so cliche; we're happy to see a blond embrace her dark side for a change. But what do we know? Vote in our poll below!
