– Three months after the Royal Wedding, the Windsors are gathering for a royal wedding: Zara Phillips, Queen Elizabeth's oldest granddaughter, today will marry British rugby star Mike Tindall in a quiet ceremony in Edinburgh, reports the BBC. The ceremony marks the first royal wedding in Scotland since the second marriage of Phillips' mother, Princess Anne, in 1992. Phillips, a noted equestrian who does not use a royal title, is 13th in line to the throne. Crowds descended on Edinburgh, hoping to catch a glimpse of more famous royals: "I do like Zara, but I'm also hoping to catch a glimpse of William, Kate, and Harry," said one watcher. Those gathered were not disappointed—William, Catherine, and Harry were spotted last night attending a pre-wedding party aboard a royal yacht. Catherine was even wearing a recycled dress, notes People. Click through the gallery for photos.
