Princess Anne is the grandmother of Savannah Phillips, Isla Phillips, Mia Tindall, Lena Tindall and Lucas Tindall.
She has been seen enjoying time with Zara’s children on a few rare occasions.
While they are not often spotted together, it is likely Princess Anne sees a lot of the Tindall’s.
This is because Zara and her family live near Princess Anne at Gatcombe Park.
When the Princess Royal is seen with her grandchildren, the expert suggested she shows a different side.
Judi explained: “With her grandchildren we do finally get to see the more demonstrative side to the Princess.
“With both Zara’s daughters having clearly inherited the tendency to look like free spirits with a huge enjoyment of life, the filter is off in terms of the way that Anne behaves towards them in public.
“It can be a joy to watch, as it does allow us a peek of the real Anne.”
“Like Zara, Anne seems happy to encourage the energetically playful side of the girls, allowing them to enjoy tearing about and having fun rather than worrying about royal protocols.
“When she made the decision to drop royal titles for her own children Anne appears to have allowed them and their own children the freedom to be demonstrative and happily playful that she and her brother Charles rarely enjoyed.”
Zara and Peter are the oldest grandchildren of Queen Elizabeth II.
Despite this, they did not receive royal titles at birth which has helped them live more privately than others in the Royal Family.
The royal line of succession – who outranks who?
The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.
It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.
Older children come before younger children. Traditionally boys came before girls, but this law was changed on March 26, 2015 before the birth of Prince William’s first child.
Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.
The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.
Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 39, his oldest son.
Then comes Prince William’s children, George, eight, Charlotte, six, and Louis, three, and they are followed by Prince Harry, 37.
