Annalynne McCord arrived at the Artists for Peace and Justice event Wednesday night with a brand new hair color. The 90210 star, who usually sports dirty blond locks, was snapped with her new dark brown 'do!

Annalynne was quick to assure her fans that she was indeed returning to 90210 with her blonde hair intact this fall. "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 posted on Twitter.

She is currently filming a movie titled Officer Down with David Boreanaz. What do you think of her darker look?
