Prince George and Princess Charlotte know how to "pop" when it comes to a royal photo op!
The royal sibs made a winning appearance in honor of Saturday's annual Trooping the Colour celebration, appearing with their parents, Prince William and Princess Kate; their uncle, Prince Harry; their grandfather, Prince Charles, and his wife Camilla; and their great-grandparents, Queen Elizabeth II and Prince Philip.
The littlest royals had the crowd charmed with their excitement as the Royal Air Force made a fly-over past the Buckingham Palace balcony.
Royal watchers have noted it was one of the children's most animated appearances ever, with People magazine reporting George was full of questions for his dad, and even mimicked the motions of an orchestra conductor as loud music blared.
The spectacular royal event honors the birth of the ruling monarch, in this case Queen Elizabeth, who turned 91 in April.
