While all eyes were on Meghan making her Buckingham Palace balcony debut, it was George, Charlotte and Princess Anne's granddaughter, Savannah Phillips, who stole the show.

Savannah, 7, first pretended she was conducting music as the national anthem played and then put her hand over the mouth of George, who appeared to be singing along, as if to quiet him.

Prince William looked at the two playful children in front of him, seemingly unamused.

\"For the royal family, that big appearance on the Buckingham balcony during the Trooping the Colour is a huge deal,\" said ABC News royal contributor Imogen Lloyd Webber. \"And everyone has to be on their best behavior.\"

The incident brought back memories of the 2016 Trooping the Colour when William, 36, was scolded by Queen Elizabeth to stand up.

William and Kate, who has been on maternity leave since giving birth to Louis, left the newborn home for Trooping the Colour as well.

The next time the public is likely to see Prince Louis will be at his christening later this summer.
