When the royal women are spotted together, body language expert Judi James explained Kate seems to play a supporting role with the monarch.
She told Express.co.uk: “The Queen’s closest friends are often given the job of ladies in waiting, when chosen to accompany the monarch to royal outings.
“When Kate accompanies Her Majesty on royal outings the body language between the two women looks similar to that between the Queen and those close supportive companions.”
While Kate has an important role in the Royal Family, she seems to have a different approach to her job than the monarch.

Their contrasting personalities could mean they are not “natural friends”, Judi commented.
Despite this, Queen Elizabeth II still looks happy to be in the company of her granddaughter-in-law.
The expert added: “Given their rather contrasting personalities it would be hard to imagine the very stoic and no-nonsense Queen seeing the rather sweet and more compliant Kate as a natural friend and confidant.
“But over their years spent together, since Kate married William, that does seem to be the nature of the relationship that has grown between them.
She continued: “Their different personalities and Kate’s polite deference signals means there is very little mirroring between Kate and the Queen but it’s interesting to see the Queen use a lot of eye contact when they are talking.
“The Queen tends to not use very much eye contact with friends and family when she’s at public events but this increased eye and face-gazing suggests she is fully engaged and appreciating listening to Kate talk.
“Both women tend to smile more in one another’s company.
“When the Queen visited Kate’s garden [at the Chelsea Flower Show in 2019] you could see the barely-suppressed excitement signals from Kate as her grandmother-in-law arrived, beaming widely.”

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 26 March 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, 38, his oldest son.
Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
