A royal expert claims Prince Harry is feeling isolated in California, longing for his old friends who have distanced themselves.

The prince of regrets.

Prince Harry reportedly misses his home country and doesn’t see his friends anymore because they don’t like his wife Meghan Markle.

“Harry is increasingly bored and looking back across the Atlantic where most of his army and school friends still live and whom he never sees because they won’t visit him in the States because they find Meghan difficult,” royal expert Tom Quinn told The Mirror on Saturday.

The New York Post reached out to reps for Harry and Meghan for comment.

Harry currently lives in Montecito, California, with Meghan, 42, and their kids — Prince Archie, 5, and Princess Lilibet, 3.

One of Harry’s longtime friends, Hugh Grosvenor, who is Archie’s godfather, got married in England last month, but Harry and Meghan didn’t go to the wedding.

A royal expert claimed the Sussexes skipped out on celebrations to avoid “disturbing everybody” at the soiree.

Harry’s estranged brother Prince William served as an usher at the wedding.

The last time Harry was in England was in May for the 10th anniversary of the Invictus Games.

At the time, Quinn told The Mirror that Harry didn’t plan to see his friends because they “are a part of the old pre-Meghan world that Harry hates to revisit.”

Quinn also claimed that Harry’s pals feel “betrayed” because he wrote about his military service “in such an unmilitary way” in his bombshell memoir “Spare.”

Furthermore, Quinn said Harry’s friends “don’t like Meghan” and blame her for transforming Harry into what they called “Harry the Hippy”.

“The truth is that Harry has reinvented himself in a way that just doesn’t work for his family or for friends from the past when he was a very different character,” the royal expert added.

Earlier this year, Harry renounced his British residency and claimed America as his home in new paperwork, in which he declared that his “new country/state” was the “United States.”

The move was backdated to June 29, 2023 — the same day he and the former Suits actress officially vacated Frogmore Cottage, which left them with no UK residence in their names.

However, it’s been said recently that Harry is looking for a new place to live across the pond.

King Charles’ former butler, Grant Harrold, told The Post that Harry had reportedly been eyeing properties in his home country.

“It’s something that he’s wanted and been thinking about. Now he’s probably made the decision that’s what he wants,” Harrold said.

Meghan, meanwhile, reportedly feels “rejected” by the UK and is focused on succeeding in Hollywood.
