Kate Middleton's First Red Carpet Outing Since Birth of Prince George Kate Middleton made her first red carpet appearance since the birth of son Prince George. The Duchess of Cambridge accompanied her husband, Prince William, to the Tusk foundation gala dinner at The Royal Society in London. Middleton, who gave birth to their first child July 22, looked stunning in a glittery floor-length, silver-sequined Jenny Packham dress that she paired with sparkly stilettos. William is a patron of the Tusk Trust, a British charity that funds conservation projects in Africa - a cause close to his heart. Danny E.
