Photos show Prince Louis being the silliest royal family member at the Trooping the Colour

• The royal family gathered in London for Trooping the Colour on Saturday.
• As usual, Prince Louis stole the show — and everyone's hearts.

Prince Louis is the people's king, at least when it comes to his public antics.

The 5-year-old prince once again stole the show, this time at 2023's Trooping the Colour, also known as the king's birthday parade, which took place in London on Saturday.

The parade has been a royal tradition for more than 260 years and was held in honor of Queen Elizabeth II before her death in 2022. This year marked King Charles' first birthday parade as monarch and involved a military procession of more than 1,400 soldiers, 200 horses, and 400 musicians, according to the royal website.

While there were many fun details and candid photos from the event, the youngest child of Kate Middleton, the Princess of Wales, and Prince William continued to make faces and have fun throughout the ceremony.

Prince Louis has always been a bit of a ham at royal events.

He's certainly not camera shy.

His reactions to the crowd at last year's Trooping the Colour were epic.

And his side-eye, in particular, is famous.

So it was no surprise we got more fun Prince Louis antics at 2023's Trooping the Colour.

He laughed with his siblings, holding his nose.

Once they were in Buckingham Palace, he told the crowd to "shush" from on high.

Things started tame when the entire royal family came onto the balcony.
