What's so funny?

Today the royal family including an unexpected appearance from Kate Middleton, stepped out to attend a service marking the centenary of the Royal Air Force. The royal family, who arrived together at Westminister Abbey looked incredible for the occasion with Duchess Kate opting for a baby blue Alexander McQueen dress, the same designer who created her outfit for Prince Louis' christening yesterday. While Megan, the now Duchess of Sussex opted for a black fitted Givenchy dress, channelling her inner Audrey Hepburn. The royals were greeted by Dean and Chapter of Westminster, before taking their seats inside. However it seemed once they took their seats and the service began, something funny seemed to catch William's eye and he tried to contain his laughter. However, his attempt to go unnoticed failed and in this hilarious clip, we see Kate catching him out and presumably quizzing him on his laughter.

Brilliant.

That quick look down makes it!

Too funny! Today marks the 100th anniversary of the RAF with celebrations continuing this evening including a parade and flypast.
