Prince William and Kate Middleton just engaged in a rare public display of affection at their recent royal engagement. The Duke of Cambridge was photographed stroking his wife’s back.

While speaking with The Sun, body language expert Judi James said that there seems to be an increase in Prince William and Middleton’s PDA in recent months, and it’s all thanks to Prince Harry and Meghan Markle. The Duke and Duchess of Sussex are known for being very affectionate towards each other.

Since Prince Harry and Markle’s PDA has been widely accepted and praised by royal fans, James said that it is possible that Prince William and Middleton have been inspired to follow in their footsteps.

“The couple might not simply be taking their lead from the intensely-tactile Harry and Meghan, but the way that the Sussex’s PDAs have been positively received might just have allowed the normally super-formal and quite traditionally royal William to relax a little and show his affection for his wife more openly now and again,” she said.

The body language expert went on to say that Prince William’s affection towards his wife in public may have also been inspired by Queen Elizabeth II. Her Majesty seems comfortable whenever she’s around the mom of three, there’s no reason for Prince William to shy away from being affectionate towards his wife.

“Kate’s profile and status as an individual within the royal pecking order does seem to have grown and it’s clear from the Queen’s body language when she’s with her granddaughter-in-law that she both approves of and feels affection for Kate,” she said.

And since Prince William and Middleton have already been married for eight years, there is no denying the closeness that they have with each other. The royal couple has also bonded strongly over their three children. And they have also dealt with all of the ongoing issues thrown at them together.

Prince William and Prince Harry are also rumored to be feuding. And the future King couldn’t be more grateful to his wife for supporting him during a difficult time.
