KP informed the world via Twitter that Markle will be attending the opening of "Oceania" at the Royal Academy of Arts on Tuesday, September 25, where she'll see contemporary and historic works of art from areas including Australia, New Zealand, Fiji and Tonga. "It'll keep us busy".
In a scene from new documentary Queen of the World, Harry (34) is seen speaking to a group of hospitality professionals who travelled from the Caribbean and spent two weeks working at the palace as part of a new scheme headed up by the queen.
The former actress appears to be wearing the same Roland Mouret dress she sported on the day before her wedding to Prince Harry, 33, so it's possible viewers will be treated to candid footage from their big day.
The programme was filmed over more than a year, with special access to The Queen, her family, her staff and her homes.
Speaking to the new recruits he says: 'Have you bumped into the Queen yet?
"Fifty-three countries, oh my goodness", the 37-year-old says in the clip above. If you suddenly bump into her in the corridor, don't panic.
Queen of the World features behind-the-scenes moments with The Queen and other members of the Royal Family, including Prince Charles and Camilla, Duchess of Cornwall; Princess Anne; Prince William and Catherine, Duchess of Cambridge; Prince Harry and Meghan, Duchess of Sussex; and the Countess of Wessex. Then he chuckles and adds, "I know you will".
