King Charles III's crowning is about to happen in four months. But after the explosive revelations in Prince Harry's memoir, "Spare," and his and Meghan Markle's Netflix docuseries, "Harry & Meghan," the big question is: will the Duke of Sussex attend the event with his wife and their kids, Archie and Lilibet?

Several royal experts and critics weigh in on the issue, saying Prince Harry may or may not attend. However, a royal historian Hugo Vickers, a royal family friend, claims Prince William's estranged brother may receive an invite but may not participate in it.

Page Six previously reported that the Sussexes would absolutely receive an invite to the coronation, and palace insiders even confirmed that it was true. However, Vickers told the publication that the prince had made it clear that he had certain conditions before he would accept the invitation.

He continued that there's always a possibility for reconciliation if both parties are willing to do so, though he's not sure if Prince Harry's side "will budge." "He's never wrong about anything. So that's not a very good start," he continued.

Vickers admitted that he personally hopes Prince Harry won't come as his attendance may only repel the attention from the ceremony. He also claimed it's why the crowned Kings and Queens don't get invites to a coronation.

Prince Harry himself answered the question about the possibility of him attending King Charles' coronation. In an interview with ITV News anchor Tom Bradby, the host asked him if he would come if he ever got an invite.

By the looks of it, the father-of-two leaves that decision up to the royal family, per Vanity Fair. He explained that there's a lot that can still happen in four months, though he never closes the door to any possibilities.

He then said that the "ball is in their court," though he didn't deny there's a lot to talk about. In fact, he's really hoping that they will be willing to have a sit-down and talk about it.

A royal source told The Sunday Times that a reconciliation meeting might happen soon, but it needs to take place before King Charles' coronation on May 6. The insider explained that though it may take "flexibility on all sides," it can still be done.

For that to happen, Prince Harry has to be in a room with King Charles and Prince Williams, along with other royal family members. It may also include some people the former trusts to assure that he's not being ambushed. Prince Harry may have the company of his former private secretary, Ed Lane Fox, and the late Queen Elizabeth's former private secretary, Lord Geidt, who advised the Sussexes.
