A royal expert is speaking out this week to say that Prince Harry will not have an easy time adjusting to his new life in Los Angeles, California, where he has moved with his wife Meghan Markle after they stepped down as senior members of the British royal family.

Tom Quinn is a royal journalist who recently spoke to palace insiders for a new book titled “Kensington Palace: An Intimate Memoir from Queen Mary to Meghan Markle,” and he predicted on Monday that Harry will be a “lost soul” in Los Angeles.

“I think Harry will be like a lost soul in the U.S.,” Quinn claimed, according to Fox News. “It will be far worse for Harry in America than Meghan in England. Because he’s not as tough as she is.”

This comes after royal biographer Andrew Morton told The Times that Harry will have a tough time dealing with the “intrusive paparazzi” in Hollywood.

“[The couple] will have to get used to the paparazzi and in Hollywood the gloves will be off,” Morton warned. “They’ll have TMZ sticking a camera in their faces saying, ‘How’s your day going?’ It will be aggressive and Harry won’t like that.”

Reports have been circulating in recent weeks that Harry is homesick for the U.K. as he continues to socially distance himself in the $18 million Beverly Hills mansion of Hollywood tycoon Tyler Perry.

“He has a lot of friends in the military community in the U.K. and of course he misses them. This is a very strange time for us all, but I think Harry is missing having a structure to his life right now,” a source told Vanity Fair.

Unlike Meghan, who grew up in L.A., Harry “doesn’t have friends” in California and currently has no job.

“So at the moment he’s a bit rudderless,” said the source, adding that Harry knows “it won’t always be like this.”

British primatologist Jane Goodall said last month that Harry was finding his new life in the states to be “challenging.”

“I don’t know how his career is going to map out, but yes, I’ve been in touch, though I think he’s finding life a bit challenging now,” Goodall said.
