Edie campbell channels joan jett with black mullet

Showjumping-socialite-turned-supermodel, Edie Campbell, channeled her inner Joan Jett on the red carpet at the opening of new Royal style exhibition, Fashion Rules. Edie first went dark at New York Fashion Week last season when she opened the Marc Jacobs show, updating her long bob with a dramatically dark new colour to complement her tough new style. For last night's party, Edie had more than a hint of Joan Jett mullet about her look - the piecey texture, the matte finish, the sweeping fringe... There  can't be many girls that could carry off the business in the front, party in the back look while still looking so achingly beautiful and cool - is there anything that Edie can't do?
