Video of Princess Catherine laughing at Prince Louis as sister scolds him goes viral

People can’t get enough of this interaction between Prince Louis and Princess Charlotte.

In a video that has more than 4 million views on X, the video shows Louis thoroughly enjoying himself while waiting to greet the crowd on the balcony at Trooping the Colour.

Trooping the Colour is a royal tradition that celebrates the king’s birthday. This year’s Trooping the Colour on June 15 also marks the first public appearance in months for Princess Catherine.

Both Princess Catherine and the king have battled undisclosed forms of cancer for much of this year.

Catherine cracked several smiles and laughs throughout the day, especially at her youngest son.

In this particular video, Louis looked at his sister as he cheekily danced to the music the band below them was playing. While Catherine laughed, Princess Charlotte seemingly attempted to keep her little brother under control by telling him to stop.

On June 14, Catherine addressed the public on Instagram for just the second time since revealing her cancer diagnosis.

“I have been blown away by all the kind messages of support and encouragement over the last couple of months,” Princess Catherine’s new statement shared on Instagram began.

“It really has made the world of difference to William and me and has helped us both through some of the harder times.”

As she continued, she said she’s not out of the woods yet, and remains patient as she continues to battle cancer.

“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,” Princess Catherine continued, “especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.”
