Royal bride Charlotte Casiraghi of Monaco channeled her grandmother Grace Kelly as she celebrated her marriage with glittering evening reception.

Charlotte, 32, donned a stunning diamond necklace once owned by the actress as she joined new husband Dimitri Rassam, 37, for the gala dinner at a private mansion on Saturday night.

The couple, who tied the knot in a civil ceremony in Monaco that afternoon, delighted royal fans by releasing a photo from the event yesterday.
