Is Prince Harry's Reunion With Prince William Making Him Question His Royal Exit? He May Have Regrets Once 'Honeymoon Phase' In The U.S. Is Over

Having second thoughts? Prince Harry's reunion with Prince William at the unveiling of Princess Diana's statue may have the Duke of Sussex debating if giving up his royal life was really worth it, a royal author speculated.

While Harry appears to be loving his life in the U.S. — ever since he, Meghan Markle and son Archie moved to California last year to start their lives anew — royal author Duncan Larcombe believes his return over the pond may have him missing his old life.

"Harry and Meghan seem to think they can co-exist in these two worlds – the world of British royals and American celebrity," Larcombe said, noting that the 36-year-old is still caught up in the glitz and glam of Hollywood life.

"Harry is loving the American life now – but he's still in the honeymoon phase," he told Closer for the magazine's July 10-16 issue. "I think coming back and seeing his brother, especially against the very moving backdrop of a memorial for their mother, will maybe make him question what he's given it all up for."

OK! reported that Harry returned to the U.K. for a second time — after his April return for Prince Philip's funeral — since he and Meghan stepped back from their royal duties and repeatedly bashed royal members to attend the July 1 unveiling of his late mother's statue on what would have been her 60th birthday.

Despite Diana's sons' strained relationship after Harry "blindsided" William with his royal step back, the brothers appeared to be enjoying one another's company at the unveiling in the Sunken Garden at London’s Kensington Palace. The two were seen smiling and greeting fellow royal members together.

While the royals put their best foot forward for the important day honoring their late mother, OK! learned that there is still a lot of work to be done in order to fix the estranged brothers' relationship — and Harry is ready to take the first step in doing so, according to a source.

Months after Harry said he believed William, 39, and Prince Charles, 72, are "trapped" in royal life and bashed their father's parenting style, the new father-of-two is apparently ready to own up to the mistakes he's made regarding the damage he's done to his relationships with his family members.

"Harry is prepared to acknowledge the role that just sheer temper played at unfortunate moments — notably in the so-called blindsiding early in 2020," royal author Robert Lacey said, referring to William's upset with the couple's departure.

However, all may not be forgiven just yet, as the Duke of Cambridge is still reportedly "absolutely furious at how Harry and Meghan have shared their views about the royal family, about their own immediate family, with the world’s press," said True Royalty TV co-founder Nick Bullen, referring to the couple's bombshell Oprah Winfrey interview and the Apple TV+ docuseries The Me You Can’t See.

Meanwhile, Meghan has yet to see the royals face-to-face since the couple's exit last year, as she remained home during Diana's statue unveiling with newborn daughter Lilibet Diana — who was born on Friday, June 4 — and 2-year-old son Archie.
