The Special Surprise Kate Middleton Received During Her Visit to the Imperial War Museum

It must be our lucky week, because Kate Middleton just stepped out for another royal appearance. After showing off her sporty side during a Coach Core event with Prince William on Tuesday, the mother of three made a special visit to the Imperial War Museum in London on Wednesday. The duchess looked absolutely stunning in a royal blue dress as she mingled with the director of the museum outside. Inside, Kate was given a special surprise as she viewed letters about three brothers of her great-grandmother, all of whom fought and died in World War I. Kate's great-grandmother, Olive, worked as a nurse during the war and corresponded with her brothers, Francis, Maurice, and Lionel, during their time in the trenches.
