The Sussexes were seemingly quietly "uninvited" from the event as the Palace confirmed only "working royals" were allowed.
"Harry and Meghan actually got the invitation and no-one has actually told them they are uninvited," a source revealed, with a second source adding, "I’m told they only found out they were uninvited by reading press reports."
Roughly 2,000 people total are expected to attend the top royal event on Sunday, September 18, including U.S. President Joe Biden, Canadian Prime Minister Justin Trudeau and French President Emmanuel Macron.
This recent snub is only the latest event highlighting the distance between Harry, Meghan and other members of the Royal family. As OK! previously reported, the duo was upset after finding out that their children, Archie, 3, and Lilibet, 1 — won't be granted the HRH titles when they are appointed Prince and Princess.
Amid the growing confusion over his role in the royal family, Harry joined his brother, Prince William, and his cousins to hold vigil for Queen Elizabeth II, at Westminster Hall. Sources close to the family revealed Harry and Meghan agreed they would do anything that's asked of them. The Duke of Sussex was even ready to ditch his military uniform, but was later allowed to wear it during the event on Saturday, September 17.
"Prince Harry was simply prepared to wear whatever his grandmother made plans for," a source revealed. "He is focused on honoring her and that's it."
Harry might only have one stronghold left when it comes to the dynamics of his relationship with the royals — his tell-all. However, the King is reportedly very unhappy about what might be found in the pages of the bombshell book.
"Once the dust settles, you can bet that Prince Harry will be summoned to speak to the King. There is no circumstance in the world where the King will not address the book before it is published," a source told OK!. "He has an obligation to protect the crown. He will beg Harry not to release the book. The bigger question is whether or not he will be able to persuade Harry to cancel it, at whatever cost."
