Prince Louis appeared to become a little tired watching Trooping the Colour today, but soon perked up when the pace of the music increased.

Prince Louis is back to his cheeky antics today, as he was seen yawning during the Trooping the Colour parade.

The six-year-old royal appeared to be bored by the display of pomp and pageantry at Horse Guards Parade, and was also spotted playing with a blind cord.

But he soon perked up and was seen dancing along during the quick march of the Scots Guards to Highland Laddie.

Appearing to be eager to get a closer look at the crowds below, Louis was also spotted wincing as he tried his hardest to open a window.

Today’s event marks the first public appearance since last year for Princess Kate, as well as for Louis and his siblings, Prince George, 10, and Princess Charlotte, nine.

George, Charlotte and Louis all looked delighted to be a part of the King’s birthday parade today.

Louis, who is the youngest of Kate and William’s children, could be spotted waving to spectators who lined the streets of London.

As he earlier waited on the steps outside Buckingham Palace, Louis couldn’t contain his excitement and took a tumble.

Louis was captured taking a slight tumble as she stood alongside his siblings and mum Kate before the spectacular military parade began. News footage appeared to catch the moment in the reflection of the impressive glass windows.

It had previously been unclear whether the young trio would attend this year, as their mother Princess Kate continues to undergo cancer treatment.

But on Friday evening, the Princess of Wales confirmed that both she and her three children would be attending Trooping the Colour today.

Alongside a new picture, the mother-of-three said: “…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.”

In a further update on her health, Kate wrote: “I am making good progress, but 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.”
