Prince Harry flashed his royal abs on Christmas Eve when he took part in a friendly soccer match in Castle Rising, Norfolk. The young royal showed off his athletic skills as he played alongside the Duchess of Cambridge's brother, James Middleton. Traditionally, Prince William also takes part in family's annual Christmas Eve match near Queen Elizabeth II's Sandringham Estate, where the royal family spends their holiday, though he wasn't present at this year's sporty match. However, he was on hand last year when Harry showed off his short-lived beard. Other royal family Christmas Eve traditions include gathering around the Christmas tree for last-minute decorations and opening presents. (The queen believes that the actual Christmas holiday itself should only be reserved for religion, not presents.) Tomorrow, on Christmas Day, Harry will be by his family's side as they make their annual trip to the Sandringham Estate's parish church.
