When the royal family get the giggles – see the best photos

Princess Eugenie and Jack had quite the star-studded bridal party. There were some famous faces including Prince George, Princess Charlotte and Mia Tindall, as well as Robbie Williams' daughter Teddy. Eugenie shared this gorgeous photo of her bridesmaids and pageboys and captioned it: "Jack and I would like to thank everyone who was involved in making our day so special and for all the wonderful wishes as we start married life laughing together."

They're usually in work mode when they're out and about on public engagements, which means being on their best behaviour and maintaining professionalism. But sometimes the royal family can't help losing the composure they're so known for and bursting into fits of giggles.

During their royal tour of Bhutan in April 2016, William and Kate attempted archery, the country's national sport. The pair looked highly amused as Kate's arrow massively missed the target and veered off course. The Duchess, in hysterics, instinctively held up her hand in apology.

These two always have a laugh on engagements! The Prince of Wales and the Duchess of Cornwall were attending The Garden Party to Make a Difference at Clarence House in 2010. They watched a performance of Henry Dagg's Cat Organ, prompting a fit of giggles.

One of the most fun engagements of the summer is the annual Braemar Games Highland Gathering. It usually marks a return to royal duties for the Queen, who spends the warmer months in Balmoral. Here the monarch is pictured laughing with her husband Philip, her son Charles and her daughter-in-law Camilla as she watched the tug of war.

The Cambridges had a grand old time at the London 2012 Paralympic Games. The couple giggled to each other as they attended a track cycling event, which also saw them take part in a Mexican wave around the Velodrome.
