The Prince and Princess of Wales are always up for a laugh - and that includes with some very famous faces.
Prince William and Princess Kate had a memorable interaction with Hollywood stars Dame Emma Thompson and Emma Stone a few years ago when they appeared together to discuss plans to host NHS Charities Together and NHS staff at a unique drive-in cinema screening of the Disney film Cruella' at the Palace of Holyroodhouse.
While the acting legends revealed a series of behind-the-scenes secrets and joked about their stunning costumes, William had a funny interaction with Emma Stone when she explained exactly how she pulled off a dangerous stunt outside Buckingham Palace.
