King Charles loves his son, Prince Harry, but is upset about some of the things he did, according to a royal expert.

Ingrid Seward, a royal biographer and editor of Majesty magazine, weighed in on King Charles' relationship with his youngest son, Prince Harry. Seward believes that His Majesty wasn't happy with what Prince Harry said about Queen Camilla in his previous interviews and book.

"I think he's very upset by Harry's behavior and especially upset by Harry's remarks about his wife, about Camilla," Seward told Fox News Digital. "Charles just has to be there with open arms. Otherwise, it's just going to make things much, much worse."

She also believes the British monarch wants his two sons to reconcile, especially with his condition. King Charles, 75, was diagnosed with some form of cancer earlier this year.

"And I'm sure he wishes that William and Harry were on better terms, but there's nothing he can do about it. It's between them. But he did say, 'Please boys, don't make my last years miserable,' which is exactly what they have done," Seward added.

The "My Mother and I" author also claimed that King Charles was sad about not seeing his grandchildren -- Archie, 4, and Lilibet, 2 -- after the Duke and Duchess of Sussex left the U.K. and moved to the United States in 2020.

"I don't think that the king would worry about Harry living halfway across the world, because it is not that difficult to get from LA to London, as we know," Seward explained. "But I think what's sad for him is that he doesn't see his grandchildren and that Harry has been such a disruptive force to the whole royal family. That doesn't stop Charles [from] loving him."

Tom Quinn, a royal biographer and author of "Kensington Palace: An Intimate Memoir from Queen Mary to Meghan Markle," claimed that Prince Harry felt betrayed by his big brother Prince William's growing closeness with their stepmom, Camilla.

"He [Harry] really distrusts that William actually gets on rather well now with Camilla -- Harry will see this as a betrayal," Quinn told the Mirror. "He was shocked when William realized that Camilla, far from being the monster they thought her when they were children, is actually a rather nice woman."

Quinn acknowledged King Charles' second wife for being a good listener. He said the Prince of Wales might have warmed up to her for being sympathetic, but Prince Harry has never moved on from the past and still blames Camilla for breaking their parents' marriage.

"For Harry, Camilla was the wicked stepmother back then, and she still is. It's all very sad, but shows that the huge geographical divide between the brothers -- Harry in America, William in London -- has become a physical manifestation of their emotional separation," Quinn said.

Prince Harry called Queen Camilla a "villain" and "dangerous" in his memoir "Spare." He also alleged that she "sacrificed" him on her "PR altar."

"She was the third person in their marriage. She needed to rehabilitate her image," Prince Harry said of Camilla.
