The upcoming event is also losing out on performances from Ed Sheeran, Adele, and Robbie Williams.
The good news is that Kylie and Dannii Minogue, Andrew Lloyd Webber, and Lionel Richie will take to the stage.
The tension between Prince Harry and his brother due to his book has created "seismic fractures."
Shockingly, the guest list is only 2,000, which is a quarter of the attendees at Queen Elizabeth II's Coronation in 1953.
However, Prince Albert of Monaco, Princess Charlene, and other foreign royals, leaders, and dignitaries will attend the event.
Additionally, Prince George is expected to play a significant part in the celebrations, making it an exciting and memorable event.
