I’m not quite sure how I missed this one.

French actress Melanie Laurent – the new face of Dior Hypnotic Poison – was the hostess for the 2011 Cannes Film Festival Opening Ceremony on Wednesday.

The ‘Inglourious Basterds’ actress looked gorgeous at the Palais des Festivals wearing a Dior Couture gown.

Her strapless black organza gown with a nude underlay was teamed with dazzling Chopard diamonds.
