An adorable video shows the moment Kate Middleton hugged a little girl who burst into tears the moment she saw her.
Kate gave the teary youngster, who was wearing a headband with union flag deely boppers and navy dress covered in patriotic motifs, a long hug and the girl started crying.
The princess, who had crouched down to speak to her, continued chatting to the girl, who nodded her head and gave a small shrug as Kate patted her back.
The little girl wore a red fluffy hairband with Union Jack flags sticking out on either side, as well as a dark blue dress emblazoned with crowns, Union Jacks and London buses.
A family member filmed the special moment at a walkabout for the Big Lunch in Windsor on Sunday.
Kate also comforted another little girl, named Lucy, who got emotional when she met the princess.
William and Kate made the unannounced appearance ahead of Sunday’s star-studded coronation concert at Windsor Castle and were seen shaking hands and chatting to revellers.
Royal super fans crowded around the couple, with William crouching down to chat to a boy and girl wearing golden crowns.
The prince and princess looked relaxed, with William telling one group of well-wishers: “Enjoy the concert tonight”.
It came shortly after Buckingham Palace issued the first public statement on behalf of Charles and Camilla since they were crowned.
A Palace spokesman said the King and Queen were “deeply touched” by the nation’s celebration of their historic coronation.
“Their Majesties were deeply touched by the events of yesterday and profoundly grateful both to all those who helped to make it such a glorious occasion – and to the very many who turned out to show their support in such numbers in London and further afield,” he said.
Heir to the throne William is to take to the stage to deliver a speech during the musical extravaganza in the grounds of Windsor Castle, with Kensington Palace sharing behind-the-scenes footage of the prince during rehearsals.
The King, Queen and royal family will join around 20,000 members of the public at the musical extravaganza to see performances by Take That, Katy Perry and Lionel Richie.
Tens of thousands turned out in central London on Saturday to see the pomp and pageantry of the coronation.
Charles and Camilla travelled through the city's streets in the Gold State Coach and taking to the Palace balcony in their glittering crowns.
More than 18 million people in the UK tuned in to watch the ceremony on TV, compared with 26.5 million for the late Queen’s funeral in September.
Earlier this afternoon, the Prince and Princess of Wales' official Twitter account released a short teaser clip as Prince William prepares to make a speech at tonight's extravaganza.
Despite the concert plans being thrown into chaos as singer Freya Ridings and BBC presenter Zoe Ball were forced to pull out, organisers have managed to find last minute replacements including London pop star Zak Abel.
Lionel Richie, Katy Perry and Take That will headline the show, along with the likes of X Factor star Olly Murs and pop sensation Paloma Faith
The concert, hosted by Downton Abbey actor Hugh Bonneville, will see Hollywood star Tom Cruise, Dynasty actress Dame Joan Collins, adventurer Bear Grylls and singer Sir Tom Jones appear by video message.
The series of pre-recorded sketches will reveal little-known facts about the monarch and will also include moments from beloved literary figure Winnie the Pooh – seemingly echoing the famous moment Paddington Bear drank tea with the Queen during her Platinum Jubilee celebrations.
