The Cambridge family took to Instagram to wish their followers a "very happy and relaxing Christmas Day" with a previously unseen photograph taken by The Duchess of Cambridge.
The black and white photo, taken in Norfolk where the family have their country home Anmer Hall, shows a heartwarming look at their life behind closed doors.
"🎄 Merry Christmas!" the caption begins.
"This photograph of The Duke of Cambridge, Prince George, Princess Charlotte and Prince Louis was taken by The Duchess of Cambridge in Norfolk earlier this year.
"We wish all our followers a very happy and relaxing Christmas Day."
In the image, Prince William can be seen giving Prince Louis, one, a loving kiss on the cheek, while Princess Charlotte, four, places a sisterly hand on young Louis' shoulder rocking a floral dress and puffer jacket.
Meanwhile, six-year-old Prince George sits on a wicker chair wearing shorts with animals printed on them and rugged up in a fleece jacket – both he and Charlotte look like they may have just swum, with their hair still slightly damp from the water.
The lovely image was shared by Kensington Palace ahead of Prince George and Princess Charlotte's Christmas Day debut where they joined the rest of the royal family on the iconic walk to the day's service at St Mary Magdalene Church in Sandringham.
Prince George and Princess Charlotte were the picture of cuteness dressed in their smart winter coats walking hand-in-hand with their parents to the Christmas Day service.
Prince Louis, one, is still too young to attend though and was likely back at the Queen's Sandringham estate.
Last week the Cambridge's annual Christmas card was shared on Twitter by some of the people lucky enough to receive one.
The gorgeous family portrait shows the family-of-five posing on a vintage motorbike and sidecar, with the colour palette of the day evidently blue!
The same week cute photographs of The Queen and her three heirs – Prince Charles, 71, Prince William, 37, and Prince George – were also shared by the Palace, showing them making Christmas puddings for the Royal British Legion, a charity which supports the Armed Forces and their families.
In two of the images, taken by Chris Jackson, Prince George can be seen getting stuck into the fruity pudding mix with a wooden spoon as his family look on adoringly.
According to the Palace, a new recipe was created for the special Royal British puddings – which were served at the charity's get-togethers over the festive season. Alongside the traditional raisins, currants, almonds and glacé cherries, this special mix also included poppy seeds as a special nod to the charity's iconic symbol of Remembrance.
