The pair have barely spoken since Harry left for the US and left his Royal duties behind.

Kate Middleton could be the key Prince Harry and Prince William reuniting amid an ongoing rift between the brothers.

Harry’s departure from the Royal Family and his Royal duties has seen him ostracized by family members with Harry’s comments since his departure certainly not helping.

Aside from one or two official events such as the Queen’s funeral and the King’s coronation, Harry and William have barely spoken to each other.

They were, however, both present for the funeral of their uncle, Lord Fellowes, in Norfolk on Friday, even if they sat separately.

One person Harry was particularly close with before his Royal departure was William’s wife, Kate Middleton. Though, even that relationship is said to have crumbled over the course of Harry’s departure and the subsequent fallout.

Now, according to one expert, Middleton is urging her husband to make up with Harry, believing a reunion would be “one less cloud hanging over” the Royal Family.

Speaking to Fox News, royal author Christopher Andersen said: “Kate was close to Harry, true. They had a special bond. They shared the same goofy sense of humor and laughed at the same jokes. Harry often said Kate was the sister he never had.”

He added: “Of course, Kate would like nothing better than to have the brothers kiss and make up. It would be one less cloud hanging over the Royal Family’s head. But above all else, Kate is loyal to her husband.”

USA reunion ruled out

It was rumored that Harry and William could bump into each other in New York next year. Harry is set to visit New York to ‘advance a number of his patronages and philanthropic initiatives’ and participate in engagements with African Parks, The HALO Trust, The Diana Award, and Travalyst.
