Princess Beatrice donned her latest unique hat this afternoon to join the racing fun during Ladies' Day at Ascot in England. She was there along with her grandmother, Queen Elizabeth, and her aunt, Princess Anne. The sporting day was also opened to Kate Middleton's parents Carole and Michael Middleton, who shared a carriage ride with the Queen to the royal enclosure. Elizabeth Hurley also dressed up to make a cameo at the exclusive event. Princess Beatrice and her sister Princess Eugenie were there at the start of Ascot over the weekend, though Kate Middleton, the Duchess of Cambridge, and Prince William haven't made a cameo. William and Kate have been plenty busy with their own social schedules, from Prince Philip's 90th birthday celebrations to the Ark dinner, the Trooping the Colour, and the annual Garter Service at St. George's Chapel. Their packed itinerary will continue with an upcoming official visit to North America.
