Her Majesty The Queen made an unexpected appearance at The Royal Windsor Horse Show yesterday to watch her pony Balmoral Leia compete.
It is well-known that the annual event is a popular fixture in the Queen's diary as she tries to attend every year.
Following huge applause as she made her way into the stadium, the Queen sat down next to The Earl and Countess of Wessex and The Countess Mountbatten of Burma to watch her granddaughter, Lady Louise Windsor, compete.
The Queen then looked delighted when she was presented with a trophy after one of her Highland ponies won first place in the show.
Her Majesty is expected to attend the show again tomorrow (May 15) for the finale. It has been reported that there will be a very special appearance by ten of the Queen's 12 great-grandchildren as they ride past in carriages.
The Queen has 12 great-grandchildren and they are: Savannah and Isla Phillips, Prince Louis, Princess Charlotte and Princess Charlotte, Mia, Lena and Lucas Tindall, August Brooksbank, Archie and Lilibet Mountbatten-Windsor and Sienna Mapelli Mozzi.
Last month, a member of the public posted footage on social media that they had filmed during a trip to Windsor Castle which showed a number of the Queen's great-grandchildren sitting in carriages - presumably practising for this exciting appearance.
Upon closer inspection, you can clearly see Prince George, Princess Charlotte, Prince Louis, as well as Savannah and Isla Phillips.
Princess Eugenie can also be seen walking with her son August which suggests the one-year-old will join his cousins.

It is thought that Prince Harry and Meghan's two children, Archie and Lili, will not appear in the carriages for The Royal Windsor Horse Show.
However, a spokesperson for the couple confirmed that they would be attending The Queen's Platinum Jubilee celebrations.
The statement said that Harry and Meghan "are excited and honoured to attend The Queen’s Platinum Jubilee celebrations this June with their children."
The Queen's granddaughter, Lady Louise Windsor, is also preparing to take on a very important role in the show.
The keen and talented horsewoman will drive the late Duke of Edinburgh's carriage. When Prince Philip passed away in 2021, he left his granddaughter one of his carriages as they shared a mutual love for the sport.
Sources have said that the plans for the show were devised to allow the Queen to attend in comfort as she can no longer stand for long periods of time.
This appearance of The Queen's great-grandchildren will be particularly exciting as it will be the first time that the ten royals will be seen together in public.
It will also be a special tribute ahead of The Queen's Jubilee as not every royal will get to stand on the Buckingham Palace balcony next month after Trooping the Colour.
It was announced last week that there would be a restricted number of people on the balcony with The Queen after the birthday parade.
A Palace spokesman said: “After careful consideration, the Queen has decided this year’s traditional Trooping the Colour balcony appearance on Thursday 2nd June will be limited to Her Majesty and those members of the royal family who are currently undertaking official public duties on behalf of the Queen.”
They went on to reiterate: “Other family members will be invited to events. We’ve always made that clear and they are likely to be public events.”
