Kate Middleton's birthday weekend was one to remember.
The Duchess of Cambridge, who turned 34 Saturday, was joined by her immediate family—mom Carole Middleton, 60, dad Michael Middleton, 66, sister Pippa Middleton, 32, and brother James Middleton, 28—on a visit to Queen Elizabeth II's Sandringham estate Sunday. The Middletons were seen walking to church with Kate's husband, Prince William, 33, for a special event to mark the 100th anniversary of the Gallipoli campaign during World War I. They were also joined by two of Princess Charlotte's godparents, Sophie Carter and James Meade.
