GWYNETH PALTROW glammed up Cannes at a Chopard bash and on the red carpet for the premiere of her new movie, 'Two Lovers,' telling ET that this is her first time at the famed film fest!

"I've never been here, no, this is my first time!" she exclaimed, before adding later, "I'm going to work a lot, and then I'm going to go home to my babies."

At the Chopard party, the golden-haired gal shone in white as she presented a Chopard trophy to OMAR METWALLY ('Rendition,' "Grey's Anatomy") while director SPIKE LEE presented another trophy to TANG WEI ('Lust, Caution').

Meanwhile, she changed into an elegant navy number for the 'Two Lovers' premiere, where she posed with famed designer VALENTINO.
