Princess Charlotte was seen telling her little brother Prince Louis to ‘stop dancing’ after the youngster starting busting out some moves during today’s Trooping the Colour.
The Wales children were standing at a window in the Horse Guards building, so they could watch King Charles inspecting the troops outside.
As Prince George, 10, Princess Charlotte, nine, and Prince Louis, six, waited by the window with their mother Kate Middleton, 42, the youngest royal started swaying his hips, much to the apparent chagrin of his older sister.
Charlotte, who has been seen issuing instructions to her brothers during previous royal events, appeared to tell her sibling to ‘stop dancing’. However, he was unreceptive to the command, and continued with his moves.Â
Meanwhile, their mother the Princess of Wales appeared to smile while watching the interaction between her children, before she regained her previous, more serious demeanor.Â

Louis is beloved by many royal fans, thanks to the spirited behaviour he has shown at previous public appearances.Â
And today has been no difference, with the youngster seen pulling faces as he took a carriage ride with his mother and siblings earlier today.
He appeared less than thrilled during the ride, at point knitting his brows as he stared out of the window, open-mouthed. Another snap of the young prince showed him frowning, with his mouth downturned.
At another point, the six-year-old appeared bored during the long, formal event, and was seen scrunching his face and playing with curtains, as well as yawning.  Â
While the Wales children were accompanied by their mother as they rode to Buckingham Palace in a carriage earlier in the day, their father Prince William took part in the parade on horseback.
And their mother’s presence was no doubt reassuring for the youngsters.
The future Queen, who only confirmed that she would be attending the event last night, was the picture of elegance and grace as she donned a crisp white structured pencil dress which had a bow along the neckline. The designer is believed to be Jenny Packham – many of whose creations Kate has donned before.
The garment featured a monochrome belted band which sat on her waist and highlighted her sophisticated frame. Kate opted for a simple black clutch bag and classy pointed white heels, which tied the chic look together.Â

After smiling at her children, the Princess of Wales quickly returned to a more serious demeanor
She wore her glossy brunette tresses in a stylish braided low-bun and completed the look with a coordinating hat by Philip Treacy, and her Cassandra Goad Cavolfiore pearl earrings, which retail for £5,620. She completed the look with her Irish Guards Regimental Brooch – a nod to her role as the regiment’s honorary colonel.
Meanwhile, Prince George wore a navy suit with a crisp white shirt and royal blue tie, and a pair of black lace-up shoes. His younger brother Louis wore a navy blazer and shorts, with a white shirt and royal blue tie, and a pair of loafers.Â
Princess Charlotte wore a navy dress in a sailor-style design, and white strap shoes.Â
Ahead of her appearance, the Princess penned a moving personal message thanking the public for their support over her cancer diagnosis and revealing she is looking forward to attending the traditional ceremonial day.
Back in March, the Princess disclosed she was undergoing ‘preventative chemotherapy’ for an undisclosed form of the disease says her treatment is ongoing and will be for several months to come.

While she will not be returning to public duties full-time, she revealed that she does now feel well enough, however, to undertake a small number of public engagements in the coming months.
To mark the news Kensington Palace have also released a stunning new portrait of the princess taken at Windsor this week by Matt Porteous showing her looking well and in a reflective mood.
In her message the Princess says she has been ‘blown away’ by all the kind messages of support and encouragement over the last couple of months.
‘It really has made the world of difference to William and me and has helped us both through some of the harder times,’ she wrote.
Movingly she reveals she is making ‘good progress’, but adds: As anyone going through chemotherapy will know, there are good days and bad days. On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well.’

She added: ‘My treatment is ongoing and will be for a few more months. On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home.
‘I’m looking forward to attending The King’s Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet.
‘I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.
Thank you so much for your continued understanding, and to all of you who have so bravely shared your stories with me.’
The Princess first announced that she had cancer on March 22.

In a hugely moving video statement, recorded at Windsor, she revealed that she had been diagnosed following serious abdominal surgery in January and was already undergoing ‘preventative’ chemotherapy.
In a deeply personal, unprecedented and emotional video message filmed just two days earlier, Catherine revealed the news had come as a ‘huge shock’ and that she and William ‘have been doing everything we can to process and manage this privately for the sake of our young family’.
‘It has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok,’ she said.
‘As I have said to them; I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits. Having William by my side is a great source of comfort and reassurance too. As is the love, support and kindness that has been shown by so many of you. It means so much to us both.’
Kensington Palace said at the time that it would not be sharing details of what kind of cancer the princess has, or what stage of cancer it is and asked people not to speculate.
At the time of her abdominal surgery in January, Kensington Palace said that it was non-cancerous. They confirmed again in March that is the case and that no tests had confirmed the presence of cancer. However post-operative tests subsequently found that cancer ‘had been present’.
A week ago, the royal apologised for missing out on a key rehearsal for the event, writing a letter to the Irish Guards, saying: ‘I hope I am able to represent you all very soon’.
