The royal family is celebrating Easter, which doubles as the queen's 93rd birthday. Queen Elizabeth II was all smiles during an Easter Sunday service at St. George's Chapel at Windsor Castle. She donned a pastel blue coat, a bright pink dress and matching hat, a trend among the royals, while holding a vibrant floral bouquet. Sunday is the first of two birthday celebrations each year for the queen, a tradition that dates back more than 250 years to King George II. She marks her official birthday in June with the Trooping the Color parade.
