Adorable footage has emerged of what appears to show the Queen's great grandchildren sitting in a horse-drawn carriage at Windsor Castle.
The video has been circulating on social media and shows the youngsters sitting on a horse-drawn carriage in the castle's Quadrangle.
It's difficult to make out exactly which of the Queen's 12 great grandchildren are on the carriage but Prince George, Princess Charlotte and Prince Louis all appear to be there.
Standing to the right of the carriage appears to be their mum the Duchess of Cambridge, while Princess Eugenie holds on to her young son August's hands as he toddles around on the grass.
Princess Beatrice's husband Edoardo Mapelli Mozzi also appears to be taking photos of the carriage, while a dog can also be seen running underneath the carriage.
One of the Twitter accounts that posted the footage, The Cambridges News wrote: "So excited!!! The Queen's great grandchildren at Windsor Castle!!! For sure we will have a new portrait for Platinum Jubilee. This will be awesome.
"Or maybe they are practicing in the carriage for Trooping the Colour? What do you all think?"

One wrote: Ahh imagine how cute those pictures are. I think they were practicing to be on a carriage for Trooping the Colour."
Another said: "How lovely and
a good memory for the children."
One tweeted: "How wonderful! So excited to see the results of the pictures! The platinum jubilee is going to be amazing."
While another fan added: "Awww that's brilliant...I bet that took a lot of effect especially with the younger ones!"
The footage emerging comes just days after reports that Prince William and Kate's children George, Charlotte and Louis will have "starring roles" in the Queen's upcoming Platinum Jubilee celebrations.
According to the Telegraph, the three Cambridge children will all take a “visible” part in the Jubilee celebrations, which are set to take place in June.
The publication says fans could look forward to them taking part in carriage rides at Trooping the Colour.
Louis, the youngest of the three who turned four at the weekend, is now the same age as his dad when he first rode in a carriage at Trooping the Colour in 1987 alongside his mum Princess Diana and great grandmother the Queen Mother.
