The late nights with newborn Prince Louis are clearly catching up with Prince William. The dad-of-three was caught with a case of the giggles on Tuesday morning ahead of a church service at Westminster Abbey.
The Duke and Duchess of Cambridge stepped out for the service honouring the Royal Air Force centenary.
Ahead of the function, William and Kate were spotted patiently waiting for the ceremony to begin when he broke a smile, which quickly grew into a giggle.
But when his wife took note of the laughter, he became silent. The camera panned out and it appeared William let The Duchess in on the joke.
In the short clip, you can see a smile come across Kate’s face as well.
Kate looked stunning in a pale blue Alexander McQueen frock and a matching fascinator.

It’s not the first time William has been spotted breaking royal protocol at Westminster Abbey. Shortly after Prince Louis’ April 23 birth, Prince William was spotted nodding off during the annual Anzac Day Service Of Commemoration and Thanksgiving.
