Kate Middleton and Queen Elizabeth have known each other for years. And there are reports claiming that they are actually very close.

While speaking with Express, body language expert Judi James said that there’s one thing that the Duchess of Cambridge does whenever she’s with Her Majesty that proves their closeness. Prince William’s wife usually makes very long eye contact with the monarch.

“ Kate is one of the few people the Queen seems to use prolonged bouts of eye contact with, making them look very chatty together, leaning head-to-head and with the Queen often being the one using signals of intense listening, suggesting it’s Kate doing the entertaining,” James said.

But even if this is the cast, Middleton still isn’t the Queen’s favorite granddaughter-in-law. The special title has been given to Sophie, Countess of Wessex. According to a palace insider, Her Majesty trusts Sophie far beyond her trust for Middleton, Camilla Parker Bowles, and Meghan Markle.

The insider also said that the Queen makes it a point to hang out with Sophie whenever she and her family are in Balmoral. The monarch has also developed a special bond with Sophie’s children, Lady Louise and James.

Meanwhile, the mom of three also made headlines this week after it was revealed that she, Prince William, and Prince Harry made such a great team before Markle joined the Royal Foundation. On the podcast “Images of Diana,” host Natasha Kaplinsky called the trio a “united force.”

“They know the power of their brand don’t they and in their charity work, they have coordinated their efforts very successfully recently into a foundation. It’s run by the Duke and Duchess of Cambridge and Prince Harry. They, like Diana, seem to have focused on causes now, rather than individual charities,” she said.

Royal expert Sarah Gristwood agreed with the host by saying that three royals have worked as a triple act before Markle took part in the Royal Foundation.
