Prince William and Kate said the concert was a "fitting and fabulous" tribute to the Queen
Prince William and Kate shared a clip of highlights from the event on their Instagram feed, which showed them taking their seats in the royal box, the Duke going up on stage to give his speech, and photos and video clips from the three-hour concert.
"What. A. Show. Tonight's #PlatinumJubilee Party at the Palace was a fitting and fabulous tribute to Her Majesty. Well done to everyone involved!" it was captioned.
The Cambridges certainly looked to be enjoying the concert, which featured performances from the likes of Queen and Adam Lambert, Sir Elton John and Alicia Keys.
The royal couple attended the event with Prince George and Princess Charlotte
While Prince George and Prince William were seen waving flags and singing along to Sir Rod Stewart's rendition of Sweet Caroline, Princess Charlotte and her mum were also seen sharing an adorable duet as Diana Ross closed the show at the end of the night.
The family have played a key role in the Queen's Platinum Jubilee celebrations over the last four days; as well as attending Trooping the Colour and joining the Queen for a balcony appearance at Buckingham Palace on Thursday, they also carried out an engagement in Cardiff earlier on Saturday, which marked Prince George and Princess Charlotte's first official visit to Wales.
On Friday, Prince William and Kate also attended a special service of thanksgiving for the Queen at St Paul's Cathedral alongside royals including Prince Charles and the Duchess of Cornwall, the Earl and Countess of Wessex, and Prince Harry and Meghan Markle.
