Buckingham Palace is reportedly preparing for Prince Harry and Meghan Markle's possible arrival at Windsor Castle to witness King Charles III's coronation on May 6. Does this serve as a hint that they will possibly attend the historic event?

Despite Prince Harry and Meghan's strained relationship with the royal family, King Charles allegedly still wants his son and his daughter-in-law to witness this special occasion in his life. However, it remains to be seen if the couple will show up.

Daily Mail reported that the palace's staff has already begun "organizing logistics for the historic occasion." Part of the instruction is said to include the Duke and Duchess of Sussex in the program, though there are no words yet if they will arrive.

An insider revealed the pair is being considered in all the planning for the big event, from the cars they will use to the seating plans to dining arrangements and more. Though this isn't a confirmation if they have accepted the invite and may just be a preparation for their possible arrival, the tipster is confident that their answer is "not a no."

The staff is working on the expectation that Prince Harry and Meghan are coming, as these arrangements should be made in advance.

For starters, the controversial duo's spokesperson revealed they had received invitations to King Charles' coronation via email. However, at the time, the rep said they had yet to make an immediate decision on whether they would come, so no official confirmation was disclosed.

It has been known that Prince Harry and Meghan's relationship with King Charles, Camilla, Queen Consort, Prince William, and Kate Middleton have been cold over the years. Things get even worse with the release of their Netflix docuseries "Harry & Meghan" and his memoir, "Spare," making several allegations against the royal family and the monarchy.

Despite that, an alleged person close to His Majesty claimed he still wanted to reconcile with his youngest son. The insider told The Telegraph that the king had always made it clear how much he loved his boys, keeping his communication channels with them open throughout the years in spite of the many barbs in California.

The monarch had also reiterated that Prince Harry and Meghan would always be welcome in the U.K. anytime. That said, he had fully planned their attendance at his coronation and would love to see them witness the special occasion.
