Prince George, Princess Charlotte and Prince Louis have wished their "Papa", Prince William, a happy Father's Day.
The post on the Prince and Princess of Wales's official social media pages features two photos - captioned "before and after".
The children are seen hugging their father - and then piling on top of him.
The post reads: "Happy Father's Day, Papa (before and after!) We love you! G, C & L."
The two photographs of the family - one colour and one black and white - were taken earlier this year in Norfolk by photographer Josh Shinner, who also took Prince Louis's birthday portraits earlier this year.
The post follows yesterday's Trooping the Colour, celebrating King Charles's official birthday, after which the family shared a rare posed photo taken on the day of the event.
The first photo shows the Prince of Wales wearing a green woollen jumper and jeans, with his arms around George, 11, and Charlotte, 10, with Louis, seven, standing in front of him.
The second picture shows everyone in a bundle, lying on grass and daffodils, with Prince William at the centre.
The Royal family traditionally shares public wishes for Father's Day and Mother's Day.
Last year, the Prince of Wales shared a photo of himself playing football with the King, taken in the gardens of Kensington Palace in June 1984, just ahead of his second birthday.
This year, Buckingham Palace posted a black and white photo of Prince Philip pushing a young King Charles and Princess Anne on a swing.
A second photo showed the Queen and her father, Major Bruce Shand, taken on the day of her wedding to Charles in 2005.
The message read: "To all Dads everywhere, we wish you a happy Father's Day today."
