The Prince and Princess of Wales have revealed what went on behind-the-scenes at the Coronation concert with a slick video as it emerged they also hosted a secret after-party.
The clip was posted to William and Kate's social media accounts just hours after they and other royals danced the night away to the likes of Lionel Richie, Katy Perry and Take That at the Windsor extravaganza.
In a big royal sing-a-long, Princess Charlotte and Prince George waved their flags enthusiastically and swayed in time to the music.
The princess also sang the words to Katy Perry’s Roar and Firework, as the US singer took to the stage in a shiny gold metallic ball gown.
And in the slick clip shared by William and Kate, it shows the family taking their seats in the royal box before the gig started before showing shots of flag-waving fans in the audience.
It also shows what went on behind the scenes as William took to the stage to give a heartfelt speech paying tribute to his father King Charles, where he said: "Pa, we are all so proud of you."
It also shows the performance of Lionel Richie, Katy Perry and Take That before ending on a sweet shot of the family all dancing, waving their flags.
The video was shared as it also emerged that William and Kate hosted a secret after-party following the concert, which was also attended by Prince Edward, Lady Louise Windsor and Sophie, the Duchess of Edinburgh, who delighted royal fans with her dance moves.
The party was revealed in the Court Circular, a record of royal engagements, which stated: "The Prince and Princess of Wales this evening held a reception following the concert at Windsor Castle at which the Duke and Duchess of Edinburgh and the Lady Louise Mountbatten Windsor were present."
It comes after Olly Murs, one of the other performers at the concert, let slip there had been an after party he had been invited to during an interview on Sky News but admitted "he didn't know how".
The sun shone for crowds at Windsor Castle for the Coronation Concert – with cheers lasting as the day turned to night during the star-studded show.
Today, the Coronation festivities will continue on the Monday bank holiday to celebrate the King’s coronation with the Big Help Out.
The King and Queen will not be appearing publicly on Monday – the day of the Big Help Out, which is billed as a lasting volunteering legacy to mark Charles’s crowning.
Other royals will be out and about with the Duke and Duchess of Gloucester visiting the Coptic Orthodox Church in London where young volunteers will be hosting a coronation street party.
Prince Edward and Sophie will take part in a puppy class at the Guide Dogs for the Blind Association Training Centre in Reading.
The Big Help Out day is organised by The Together Coalition and partners such as The Scouts, the Royal Voluntary Service and faith groups from across the United Kingdom.
