On the final day of the Cannes Film Festival, the jury member pulled out all the stops to claim the red carpet. She wore a custom-made white silk gown by Giorgio Armani on her last walk down the carpet to both the Zulu premiere and the closing ceremony. Her dress featured a V-neck bustier with a gold bow made out of Swarovski crystals, which somehow complemented her Harry Winston jewels. She painted her lips bright red, but aside from the dress, the most scene-stealing part of her look that evening was her hair: a wild lump of braids and twirls fashioned into a mega bun. Very Game of Thrones–y, right?
