The picture, taken by Josh Shinner in Norfolk in April, was posted on Kensington Palace's social media with the caption: 'Wishing everyone a very Happy Christmas.'
The image shows William and Kate smiling as they sit on the grass amid spring daffodils with their children, with the Princess also seen with her arm around George.
Charlotte is resting her head on her father's shoulder and holding onto his arm, while a relaxed Louis - without his top front teeth - is leaning back between William's legs.
The picture appeared to be from the same photoshoot by Mr Shinner used to capture portraits for George's 12th birthday in July and Louis's seventh birthday in April. Read more @ https://tinyurl.com/yu635hwd
