Prince William and Camilla could be seen getting closer to Charles to hear the funny story, and the Queen's eldest son definitely had a hard time explaining it whilst laughing uncontrollably.

While it's not exactly known what was so funny, his gestures seem to indicate that the act below had managed to bump into another accidentally.

The pageant was great for royal viewers wanting to see how the royal family interact together- one particular favourite moment with fans was when Prince Louis ran to sit on his grandfather's lap.

The heir to the throne could then be seen rocking the four-year-old from side to side in time to the music and pointed out scenes as the parade passed by the royal box on the final day of the celebrations.

Another sweet moment saw Louis give his mum Kate a kiss on the royal box.

Louis, four, and Kate were joined by Prince William, Prince George and Princess Charlotte, as well as Prince Charles and the Duchess of Cornwall among other senior royals for the spectacular event.

The parade marked the closing of the four-day celebration which honoured the Queen's remarkable 70 years on the throne.
