Prince William and his new wife are attending their first official engagement as a married couple.

The Duke and Duchess of Cambridge, as the couple is officially known, are the guests of honor at a charity gala dinner on the grounds of Kensington Palace.

Guests clamored to snap photos on their smartphones of the former Kate Middleton, who cut a glamorous figure in a dusty pink, sparkling Jenny Packham gown.

The benefit for the charity Absolute Return for Kids, also known as Ark, attracted a who's who of Britain's rich and famous.

Tickets for the black-tie event reportedly went for 10,000 pounds ($16,400) a head.

William and Kate were married in a lavish ceremony on April 29 at Westminster Abbey.
