Cameras captured Prince William and Princess Kate with their fingers linked as they descended the Royal Dais at Datchet Road at Windsor Castle. The sweet move might have been to help Princess Kate keep her balance as she navigated the stairs, as she wore heels for her meaningful debut in a Christian Dior.

Princess Kate joined her husband Prince William, King Charles III and Queen Camilla on Tuesday as they kicked off France's state visit to the U.K. The royals gathered at RAF Northolt in Windsor, England, to welcome French President Emmanuel Macron and his wife Brigitte at the start of their three-day state visit.
