Expert Judi James told Daily Mail said of Kate and Meghan, "It reminds me of political body language. The kind of thing politicians do when they're walking with other heads of state and want to show some signs of rapport or unity."
But, a video that has surfaced online shows a subtle gesture that proves the pair are not feuding.
The footage shows Meghan talking to fans during the Royal Family's walkabout. The pregnant duchess then goes over and holds her position to wait for Kate.
Meghan is then seen placing her hand on Kate's back so the pair move together down the road.
The subtle gesture was picked up by fans, who believe it proves the royal pair are really friends.
According to reports, prior to Christmas day the Queen and Prince Charles made it clear that any rift between the two duchesses must be kept out of the public eye as they arrived together at the St Mary Magdalene Church.
