Like grandfather, like grandson!
In the BBC special Elizabeth at 90 - A Family Tribute, commemorating Queen Elizabeth II's 90th birthday, her grandchildren Prince William, 33, and brother Prince Harry, 31, watch a home video of her son and their father, Prince Charles, toddling around as a small child in a garden at Windsor Castle.
"He walks like George!" Harry says, referring to William and wife Kate Middleton's eldest child, son Prince George, 2.
"He does," William replies.
"Or George walks like him," Harry continues.
"There's a purpose to the walk," William says.
"We've probably chased each other around that garden a few times as well," he adds.
"Yeah, not for a while though," Harry responds. "In the early days when Gan-Gan was around."
He is referring to their grandmother's mother, Queen Elizabeth The Queen Mother, who died in 2002 at age 101. George calls William's grandmother the queen Gan-Gan as well.
The footage also shows Charles with his mother and one of his siblings, who is sitting in a baby carriage. The prince, now 67, has a younger sister, Princess Anne, 65, and two younger brothers, Prince Andrew, 56, and Prince Edward, 52.
The queen, Charles, William and George recently posed for a four-generations family photo that was made into a new batch of official Royal Mail stamps in the U.K., marking the first time the little prince has gotten his own stamp.
Elizabeth celebrated her 90th birthday Thursday. The Elizabeth at 90 - A Family Tribute special is set to air Thursday in the U.K. on BBC One at 9 p.m. local time.
The program also contains more never-before-seen home videos from the queen's personal collection, some of which were filmed by her, her husband Prince Philip, 94, and her late parents King George VI, who died in 1952 at age 56, and Queen Elizabeth The Queen Mother.
