Prince Louis shared a charming moment with his older brother, Prince George, during this year’s Trooping the Colour, according to a lip-reading expert.

The royal family stepped out under clear skies for King Charles’ official birthday parade in London. Crowds lined the streets surrounding Buckingham Palace, hoping for a glimpse of the royals during the grand celebration.

At the start of the festivities, the Princess of Wales, 43, was seen riding in a carriage alongside her three children: Prince George, 11, Princess Charlotte, 10, and Prince Louis, 7.

Prince William, 42, rode on horseback, joined by his sister Princess Anne and brother Prince Edward. King Charles, 76, and Queen Camilla, 77, were also seen travelling in a separate carriage.

Louis and George’s Sweet Exchange

As the royal procession made its way from Buckingham Palace down The Mall toward Horse Guards Parade, Kate and her children waved warmly to the cheering crowds.

George and Louis sat beside each other during the ride and were seen exchanging quiet words as the parade unfolded.

Lip reader Nicola Hickling, speaking with The Sun, revealed a tender moment between the brothers. According to her, Louis asked, “Should I wave?”

George is said to have replied, “It’s up to you, I can’t believe how sunny it is.”

Louis then added, “Let’s do it together.”
