All we can say is wow. Charlize Theron stunned at today's premiere of Mad Max: Fury Road during the the 68th Annual Cannes Film Festival, as she glided down the red carpet accompanied by her beau Sean Penn.

For the occasion, the actress donned an eye-catching sunshine yellow Christian Dior Couture gown that featured a sculptured scoop neck and flowing train. She completed her look with dazzling Chopard jewels, a glamorous updo, and barely-there makeup. This is one movie star moment we won't forget anytime soon.
