CANNES WATCH: Celebrities douse in diamonds at the De Grisogono soiree

CANNES, France - Celebrities were dousing in diamonds Tuesday at the glitzy De Grisogono soiree — one of the social event highlights of the Cannes Film Festival.

At the exclusive Du Roc hotel in Cap D'Antibes, stars such as Natalie Portman, Antonio Banderas, Mary J. Blige, Adrien Brody, Michelle Rodriguez and Paris Hilton filed through to a garden party that was themed "Divine."

True to the promise, guests were treated to a bejeweled fashion show and an illumination display with cases of sparkling jewels bewitching the forest setting.

Though guests were here to party, some didn't forget one of the trending issues at this year's festival: Raising awareness about the dearth of female directors.

Blige, who wore a black cady floor-length evening gown from Emilio Pucci, said that it was "absolutely an important issue. We've still got so much work to do."

In the fashion stakes, model of the minute Cara Delevigne was a standout — wearing lashings of emeralds, diamonds, and rubies, twinned with a Grecian white draped gown.
