Ever since Meghan Markle married Prince Harry last May, rumors have been swirling that she does not get along well with her sister-in-law, Kate Middleton. Now, royal expert Katie Nicholl is speaking out to reveal that while she believes these rumors have been overblown, she does not think that Meghan and Kate will ever be “best friends.”

“I think this idea of there being a catfight between the two duchesses has made tantalizing headlines, but I don’t believe that,” Nicholl said. “I’ve never heard from my sources that there has ever been a feud or a falling-out.”

Though she does not think that Kate and Meghan despise each other as much as

“I had heard about an upset over the dress fitting for Princess Charlotte,” Nicholl said, referring to Meghan allegedly making Kate cry in the lead-up to her wedding. “And I had heard that while Harry was very keen for the two of them to become best friends, there was never that sort of a friendship.”

“I know in the early days Kate invited Meghan over to apartment 1A for tea. Obviously, she took her on that high-profile trip to Wimbledon, so they have spent time together. But what I think hasn’t happened is — they haven’t become best friends out of all of it,” Nicholl continued. “That’s not to say they hate each other. I don’t believe that to be the case at all.”

Nicholl added that both Kate and Meghan have realized by now that they are two very different women from completely different backgrounds.

“They quite quickly realized they were two pretty mature women — quite different women — and really the only thing they had in common was they’d married princes,” she explained. “Not just Prince Harry, I think probably the world wanted them to become best friends.”

The royal expert said that she believes reports that William and Harry have had some issues with one another recently, which has not made the situation between their wives any easier.

“I do think there is some truth to there having been some tension — not just between the duchesses but between the dukes, as well,” she said. “As we all know, things can gather momentum pretty quickly. So while I think there’s been tension, I don’t believe there has been some feud.”

Nicholl concluded by saying that going forward, she fully expects Meghan and Kate to get along since it is in both of their best interests to do so.

“I do know that Meghan and Kate have come to an agreement to get along, to make an effort, to be amiable and warm toward each other in public,” she said. “They both realize it’s in neither of their interests to have these catfight headlines. It’s not what either of them want.”
