Princess Mary and Prince Frederik Pictures With Children Christian, Isabella, Vincent and Josephine

Princess Mary celebrates her 41st birthday today! The Australian beauty won the heart of Denmark’s Crown Prince Frederik in 2000, when they met at the Slip Inn in Sydney during the Olympics, and she has since led a charmed and charitable life as one of Europe’s beloved royals. Mary and Frederik were married on May 14, 2004, and are now the proud parents of four adorable children: Prince Christian, 7, Princess Isabella, 5, and twins Prince Vincent and Princess Josephine, 2. To celebrate Mary’s birthday, we’re taking a look back at some sweet moments with her family — and we’re wishing her a great one!
