It’s probably too late, Harry.

One month after his explosive tell-all interview with Oprah Winfrey, Prince Harry is reportedly feeling “embarrassed” and “regretful” about it, according to his royal biographer.

Duncan Larcombe, who wrote the book “Prince Harry: The Inside Story,” told the UK’s Closer Magazine that Harry only lashed out at the royal family because “he’s a hot-headed guy.”

“Harry was clearly hurt and angry about Meghan’s experience with the royals — and used the interview to get it out,” Larcombe explained. “But after returning home, I’ve no doubt he’s been feeling embarrassed, regretful, and awkward.”

“He’s now facing the consequences. I believe he’ll regret that interview — and maybe his decision to leave the royal family,” the royal expert continued, going on to say that it was clear Harry was “feeling numb” as he returned to Los Angeles from the funeral of his grandfather, Prince Philip, earlier this month.

“You could see in his face at the funeral that he was torn,” Larcombe said. “Coming home has reminded him of everything he’s sacrificed in recent years — and of the recent damage done.”

Harry’s feelings could not be more different from those of his wife Meghan Markle, however, who Larcombe said is “elated” and “in her element” living in California.

“Her dream was always LA. So these two feelings — Meghan excited for their future and Harry nostalgic for his old life — are bound to cause tension for them,” the royal author said.

Another source said that Meghan is ecstatic to be living her Hollywood dream.

“While Meghan’s focusing on her pregnancy, she’s also excited about the future and throwing herself into all these new projects. She has so many ideas and goals she wants to achieve – so it’s all really positive for her,” the insider said. “She’s got a nice set of A-list celebs in her circle – Gayle King, Chrissy [Teigen] and, of course, Oprah. She’s loving their new life and she’s excited for her and Harry to establish themselves as a top celebrity couple in Hollywood.”

In the end, Larcombe does not see this all working out for Harry in the long run.

“I can’t see how Harry can live this new life and keep things harmonious with his family,” Larcombe continued. “lose-lose situation.”

“I just don’t think that Harry will be able to live harmoniously as a part of these two worlds — the royals and the L.A. showbiz world,” he said. “He’s in for a very difficult ride. There could be tough times ahead.”
