The royals have shared a picture of Prince George’s hand-painted Christmas card, as they gather to celebrate the festive day.
The nine-year-old Prince’s card features a reindeer with snow on its nose and two robins perched aboard its antlers and back.
A message on Kensington Palace’s official Twitter account said: “Happy Christmas! By George.”
The young prince joined his seven-year-old sister Princess Charlotte and their parents, the Prince and Princess of Wales, at the Together at Christmas Carol Service at Westminster Abbey in London on Christmas Eve.
The family, including four-year-old Prince Louis, will join the King and Queen Consort at Sandringham on Christmas Day for the first time in three years, in the family’s first Christmas since the death of Queen Elizabeth II.
King Charles III will make his first Christmas broadcast later today, in which he is expected to pay tribute to his late mother.
Painting runs in the royal family, with the King known to have an artistic streak.
Charles has previously described how he finds painting so relaxing that it “transports me into another dimension”.
Earlier this year, 79 of Charles’s watercolours – the first full exhibition of his work in the medium – were exhibited at the Garrison Chapel in Chelsea, south-west London.
The atmospheric paintings depicted Scottish landscapes such as the Huna Mill in John O’Groats and Glen Callater near Balmoral, as well as outdoor scenes from Provence in the south of France and Tanzania in East Africa – one of his favourite places to paint.
George’s great-grandfather, the late Duke of Edinburgh, was also interested in art and design, having painted mostly landscapes in oils, according to the Royal Collection Trust.
One such picture, featured on the trust’s website, is Duart Castle from the Sound of Mull.
It was painted during one of the Royal Yacht Britannia’s summer cruises around the Western Isles, the trust said.
