Prince Harry has adopted a more American persona, with a growingly irritable and rough attitude, as friends characterize him as a “petulant boy” sending arrogant WhatsApp messages!

Prince Harry is “an angry boy” in America, according to his close pal who claims he’s one of the few who’s received “the odd WhatsApp” message from him.

The Duke of Sussex, 39, has been living in the US for more than four years after he and his wife, Meghan Markle, turned their backs on royal life.

Now, it seems as though Harry’s friendships are slowly but surely dwindling, according to one of the prince’s former close pals.

“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.

“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.”

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

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

Unsurprisingly, Harry’s circle began to rapidly shrink after he and the “Suits” alum, 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.

Another one of Harry’s pals told the outlet that some of the royal’s former friends still can’t get over his decision to air dirty laundry about his time in the palace.

“I can’t believe he’d stoop so low,” said the pal. “It’s outrageously disloyal. Oprah, Netflix and then the book? Three strikes and you’re out.”

“Harry and [his wife] Meghan could have left with dignity and decency and not trash the institution,” another friend of William’s and Harry’s told the outlet. “The conclusion is they’ve made money from trashing his family.”

Indeed, Harry did just that in his Netflix docuseries “Harry & Meghan,” in which he admitted, “I miss my friends … I’ve lost a few friends in this process.”

Instead, Harry has embraced life in the US — so much so that earlier this year, he sensationally renounced his British residency and claimed America as his home in paperwork.

Prince Harry has certainly made a significant transition in his life by moving to America with his wife, Meghan Markle. While some of his friendships may have dwindled, it is clear that he is forging a new path for himself in the US. Harry’s decision to step back from his royal duties and speak out about his experiences has certainly caused a stir among his former circle. Some may view his actions as disloyal and disrespectful to the royal family, while others see it as a necessary step towards finding his own voice and independence.Despite the controversy surrounding his choices, Harry seems to be adjusting well to his new life in America. He has embraced opportunities such as the Netflix documentary and his upcoming memoir, showing that he is determined to make a positive impact in his own way. While some may criticize his methods, it is undeniable that Harry is carving out a unique path for himself beyond the constraints of royal tradition.As Harry continues to navigate his new life in the US, it is clear that he is prioritizing his own happiness and fulfillment. While some may question his motives and actions, it is important to remember that everyone has the right to choose their own path in life. Harry’s journey may be different from what was expected of him, but it is ultimately his own to explore and define.
