I've been waiting for this moment all week. Here's my girl Diane at the Inglorious Basterds premiere at Cannes. She looks like royalty in her ivory silk chiffon cowl back Marchesa dress with silver hand embroidered detail. Wow, Diane, Marchesa, Cannes — it's too good to be true. The cowl back adds some sexy drama, while the overall fit is delicious. Her star and crescent diamond earrings are also lovely. Done.
