Scarlett Johansson has never been shy about changing her hair. The sexy star — most recently a blonde — has rocked long brunette locks, light and edgy bobs and even platinum styles. But Saturday night, at the White House Correspondents’ Dinner in Washington, D.C., she shocked us a little with her brand new auburn tresses. Johansson — who left an after-party hand-in-hand with rumored beau Sean Penn — beamed as she walked the red carpet in a greenish-gray Elie Saab dress, the perfect complement to her glowing skin and newly red locks. The actress joins the ranks of other new redheads like Blake Lively and Drew Barrymore. Do we have a hot new hair trend on our hands? Tell us: What do you think of Johansson’s new hair color?
