Prince William and his wife, Kate Middleton, boarded the Royal Yacht Britannia, which was docked in Edinburgh, yesterday in order to celebrate his first cousin Zara Phillips' wedding with a cocktail party! Prince Harry was also in attendance, and he was spotted ascending the same carpeted stairs that the bride and her husband-to-be, Mike Tindall, walked up. Princesses Beatrice and Eugenie also colourfully turned out, along with the elder's boyfriend, Dave Clark. Zara Phillips and Mike Tindall will marry tomorrow at the city's Canongate Kirk, and her royal relatives will be out in full force. Kate and William often go by their titles of the Duke and Duchess of Cambridge, but their Scottish equivalents are the Earl and Countess of Strathearn. Scotland is a special place for the couple, as it's where they met and fell in love while students at the University of St. Andrews. Wales, though, has been their home as of late, as it's where William works with the Royal Air Force when not travelling with Kate for family obligations.
