The Duke and Duchess of Sussex wed in 2018 and moved to the U.S. in 2020
Prince Harry is losing touch with his longtime friends, according to King Charles’ former butler, and experts are weighing in on why the reported rift is occurring.
Grant Harrold, who worked for the monarch for seven years when he was the Prince of Wales, claims Harry has cut ties with the friends he and Prince William once shared.
"I know quite a few of Harry’s friends who don’t hear from him at all now," Harrold said on behalf of Spin Genie, according to the New York Post.
Per the outlet, the Duke of Sussex missed longtime friend Jack Mann’s wedding in July, though Mann attended Prince Harry and Meghan Markle's wedding in 2018.

Harrold also said the same distance in Prince Harry’s friendships exists in his relationship with his brother, Prince William.
"They were both very sociable boys," Harrold said. "And that’s what’s so sad about it now, how they’ve gone from best of friends to non-existent really. They have become so distant.
"I mainly worked with them when they were approaching their late teenage years and twenties. I liked the way they got on with each other. They were always having fun together and having banter. They played practical jokes and wound each other up, but it was harmless.
"They were best friends, and they had the same friends, too. You’d see them in the pubs together," Harrold added. "It was a great time for them."

Harry and Markle moved to the U.S. in 2020 after stepping back from their royal duties, but according to British royals expert Hilary Fordwich, the distance was already growing between Harry and his friends.
"Harry's friends are mostly from the prestigious Eton College, where the sons of elites are groomed for former national leadership. Indeed, 20 British prime ministers attended Eton," Fordwich explained to Fox News Digital.
"One of the very first falling outs was when he introduced Meghan to his Eton friends back in 2016 during a Sandringham country estate shooting party," according to Fordwich. "Ever since then, the friends have kept their distance as has Harry."
Christopher Andersen, author of "The King," said the physical distance contributed as well.
"When ‘Megxit’ first occurred, William and Harry's friends were forced to choose sides," Andersen said. "Even brothers like Henry and Thomas Van Straubenzee, the princes' pals since childhood, were forced to choose one over the other, causing friction in their own families.

"But time and distance have taken their toll. Harry's life is centered not in London but in California. So, logically, he has grown closer to Meghan's crowd. He can't just drive a few miles to attend a friend’s wedding in the English countryside as he did so many times in the past."
Andersen notes continued scrutiny over Harry’s relationship with the royal family makes maintaining his old friendships difficult as well.
"It's not just because thousands of miles separate Harry from his friends. Every time he boards a plane and flies back home to England, speculation about a meeting with the king and his brother runs wild," Andersen said. "There just aren't that many opportunities to interact with his old friends back in England."
