Prince Harry is feeling “more and more isolated” in sunny California, according to a new report.

The Duke of Sussex, 39, has reportedly been reaching out to his old friends in the UK — despite previously ending all communication with them after quitting royal life in 2020.

Four years after his and Meghan Markle’s trans-Atlantic move, the father of two is reportedly looking to get his social life back on track.

“Harry is feeling more and more isolated in California, which is why he has been reconnecting with old friends back home,” a source told the Sun.

Insiders close to the Invictus Games founder claim that he seems to enjoy regular solo trips to his home soil — something he’s been doing more often this year.

Last week, Harry went in full incognito mode as he jetted off to the UK for his uncle’s funeral.

The mad dash — which reportedly lasted just hours — came days after he and the “Suits” alum, 43, flew to Colombia for four days.

“The Colombia trip also really highlighted how Meghan is comfortable stepping into the spotlight, while Harry cuts a very sulky, unhappy figure in the background,” the insider told the outlet.

“He wants to carve out a way back into royal life back in the UK and is seeking counsel from old friends and associates.”

The Post has reached out to Harry’s reps for comment.

Indeed, Harry has reportedly sought out a new inner circle in Tinseltown that he leans on during times of hardship.

The circle, which boasts several A-list names, reportedly includes Hollywood music producer and film composer David Foster, whom Harry sees as a “father figure.”

What’s more, the father of two has reportedly enlisted the help of several former royal aides to “rehabilitate” his image.

After becoming increasingly frustrated with Hollywood publicists in Tinseltown, the royal reportedly touched base with several pros who could help to polish up his reputation.

According to palace insiders, Harry — who is gearing up to celebrate his 40th birthday next week — has approached an “old school” adviser known for discretion to help with the plan, which has unofficially been dubbed “Operation Bring Harry In From The Cold.”

While details about the rumored plan remain scarce, it has been suggested that King Charles’ youngest son could also be taking on “very low-key royal duties” in the near future.

But despite his hopes of rebuilding the bridges he had burned, some of the duke’s old pals have recently suggested that life in Montecito, California, has turned led him down a darker road.

“He’s an angry boy,” according to “one of Harry’s oldest friends” who spoke to the Sunday Times of London. “Things haven’t turned out how he wanted.”

Harry’s pal claimed he’s one of the very few who still receives “the odd WhatsApp from him” from time to time.

“I think he misses being over here [in Britain] desperately and wants to be admired more. Anyone who knows him feels he’d rather be top of the pops here with everyone loving him, as they do with [his older brother] William and Kate,” he added.

Unsurprisingly, Harry’s circle began to rapidly shrink after he and the former “Suits” star, 43, packed up and moved across the pond in a bid to start anew.

Their move sparked several high-publicity projects such as their six-part Netflix documentary, their bombshell sit-down interview with Oprah Winfrey and Harry’s protocol-shattering memoir, “Spare.”

They have only returned to the UK a few times since.
