Helen Mirren stuns with bold new hair color at Cannes premiere.

Dame Helen Mirren debuted her new blue hair during the Cannes Film Festival's opening night at the Jeanne du Barry premiere. The actress matched the color of her hair to her gorgeous gown and swept her locks high into a Marie Antoinette style Pouf to match the movie's French historic theme. She completed the look with a pair of towering Remy: Silver Suede & Snake platforms by luxury brand Sole Bliss retailing for £199. The festival promises a Cote d'Azur buffet of spectacle, scandal, and cinema set to be served over the next 12 days.
