Bridesmaid Princess Charlotte took a tumble as she arrived at the wedding of Princess Eugenie and Jack Brooksbank.
Accompanied by her five-year-old brother Prince George, who was acting as a page boy, the three year-old enthusiastically waved to the adoring crowds as they approached St George's Chapel at Windsor Castle, before falling on her way in to the church.
But Charlotte wasn't the only member of the young bridal party to struggle with the steps.
Page boy Louis De Givenchy also stumbled as he entered the church, falling onto his hands on the West Steps of the chapel.
However, both youngsters dusted themselves off and accompanied Princess Eugenie down the aisle.
George and Charlotte were joined in the bridal party by other royal children. Savannah Phillips, seven, and her six year-old sister Isla.
The daughters of Peter and Autumn Phillips acted as bridesmaids, alongside four-year-old Mia Tindall, daughter of Zara and Mike Tindall, and five-year-old Maud Windsor, Princess Eugenie's goddaughter.
Singer Robbie Williams' six-year-old daughter Theodora Williams also took on the role of bridesmaid.
Floral patterns were seen on belts on both the bridesmaids' white dresses and pageboys' navy trouser outfits.
Lady Louise Mountbatten-Windsor, 14, and James, Viscount Severn, aged 10, the children of Prince Edward and Sophie Countess of Wessex, were both given the role of special attendants.
As they waited the few minutes for the bride to arrive, George and Charlotte had their hands held by their nanny.
As the trumpeters took their positions to herald the bride, the future king was seen to put his hands over his ears at the noise.
