PEOPLE caught up with the La Vie En Rose star who dished about the secret to her style, gorgeous gems, her attitude about being an Oscar nominee at a recent Chopard-sponsored celebration of Marion Cotillard’s Best Actress Oscar nomination. Although the Gallic beauty is known for her distinctive sense of style, she admits she doesn’t do it alone — but don’t expect any Hollywood stylists waiting in the wings. Instead, the actress reveals that she relies on “My French publicist, who is one of my best friends. He does all that stuff!” And Cotillard was the picture of refined French elegance in a flower embellished strapless Chloe dress set off with a wealth of Chopard gems, including 50-carats of diamonds circling her wrist and a collar at her neck encrusted with a rainbow of semi-precious stones. As for her partnership with Chopard, “They’ve always supported me from the beginning,” she says. When asked about words of wisdom she’s been given about the Oscars, the star says she agrees with the advice George Clooney gave to her fellow nominee Amy Ryan. “‘It will be over in a minute. When the awards are done, they’re done, everyone goes back’” he said. “‘So just to enjoy it and don’t be too frightened.’” Somehow, though, we have a feeling this year’s Oscars won’t be the talented actress’s only chance to shine.
