A smiling Princess Charlotte looking relaxed and happy has been photographed by her mother in a new image shared as she turns six years old.
The new picture was shared by Kensington Palace the day before her birthday, but in a departure from tradition, won't be posted on their social media pages.
Prince William, as president of the FA, has lent his support to a boycott of social media until companies take stronger action against racism and abuse on online platforms.
So the image is unlikely to appear on the Kensington Royal accounts before the end of the four day boycott.
In the new picture, Charlotte is wearing a blue and pink floral dress, and has her hair loose around her shoulders.
Royal fans were stunned by the new snap remarking how "grown up" Charlotte looks.
“6 years flies by...look at this little lady ...just beautiful," one person wrote on social media.
“Wow, so grown up! You can see the young lady she will become,” another person wrote.
Charlotte looks just like dad William
Others pointed out how the young princess bears an even more striking resemblance to her father at the same age.
“Omg she is all grown up and sooo blonde... She is definitely her dad’s mini me," was one reaction.
Royal watchers found the old snap of the Duke of Cambridge at the age of ten going karting at Buckmore Park ‘Playscape’ and quickly compared it to a photo of Princess Charlotte from Princess Eugenie’s wedding. The side-by-side went viral at the time.
Royals share rare family video on anniversary
Kate is a keen amateur photographer who has turned her passion into a key part of how she and Prince William share their lives with royal watchers.
Earlier this week the Cambridges shared a video of the five of them enjoying the countryside in Norfolk, showing them taking a trip to the beach and toasting marshmallows around an open fire.
Kate has previously spoken about her love of the outdoors as a child, and how she wants to encourage her children to have the same love.
Speaking to Giovanna Fletcher on the Happy Mum, Happy Baby podcast last year, Kate said: "The simple things resonate with me the most. Life now is so busy, so distracting, the simple things like watching a fire on a rainy day, I remember that from my childhood. Going for a walk, that’s really what I try to do with my children now."
She said she was happiest when "I am with my family, out in the countryside and we are all filthy dirty".
