Prince Harry and Meghan Markle made headlines three years ago when they left the United Kingdom after a number of clashes with the rest of the royal family.

However, one royal expert recently suggested that the prince may return home as his marriage ends in divorce.

Author believes Prince Harry will "come home" without Markel

Newsweek noted that Hugo Vickers has written several biographies focused on members of the royal families and collaborated on a book with Prince Edward the Duke of Kent.

The magazine quoted Vickers as saying that he believes Harry will "come home" to Britain while Markle remains in the U.S.

"I think he'll come home and if he comes home we must be very nice to him because he won't particularly want to. He's quite angry I think," Vickers continued.

"The king has left the door wide open for him to do that and he was doing such a good job before and...he looked so happy," the author continued.

Vicker's assessment is inline with one offered by fellow royal expert Tom Quinn, who recently told The Mirror that Harry is struggling with life in America.

Quinn said the prince "is increasingly bored and looking back across the Atlantic where most of his army and school friends still live and whom he never sees because they won’t visit him in the States because they find Meghan difficult."

"The truth is that Harry has reinvented himself in a way that just doesn’t work for his family or for friends from the past when he was a very different character," the royal expert added.

Deep divisions between royal brothers

Harry has also long been estranged from brother Prince William, someone directed unflattering words towards in autobiography "Spare."

"60 Minutes" host Anderson Cooper brought up passages from the book during an interview last year, including one in which Harry described William's "familiar scowl," as well as his "alarming baldness" which was "more advanced."

Harry also alleged that William instructed him to pretend they didn't know one another while both were attending the same school.
