Happy Easter from the British royals! Prince William and Duchess Kate went to church on Easter Sunday without Queen Elizabeth II, who has been experiencing mobility problems, at St. George's Chapel on the grounds of Windsor Castle. William and Kate, known as the Duke and Duchess of Cambridge, were accompanied by two of their three children: Prince George, 8, and Princess Charlotte, 6. Also in attendance were the queen's youngest son, Prince Edward, with his wife Sophie and their children, and Princess Eugenie, the daughter of Prince Andrew. 📸: Andrew Matthew Pool, AFP via Getty Images; WPA Pool, Getty Images
