Prince William and his wife, Catherine, went for a hand-in-hand walk around Holyrood Park yesterday morning in Edinburgh. They stuck around the queen's official Scottish residence for a few days after attending Zara Phillips and Mike Tindall's wedding reception there on Saturday night. The Duke and Duchess of Cambridge were decked out in similar outfits for the stroll, both in purple cable-knit sweaters with their collars peeking out. We even had a rare glimpse at the prince in his glasses! Kate and William were soon headed back to their home in Wales. Kate was seen later in the afternoon out at her local Tesco, taking care of the grocery run while Prince William prepped for a return to work with the Royal Air Force.
