Royal fans who might be hoping to catch a glimpse of the Duchess of Cambridge will have to go without though as Kate was out of action for much of the filming, which took place over the final weeks of her pregnancy with Prince Louis, who was born on April 23.
The Duchess of Sussex was certainly the star of the show as she launched her first solo project and the Duke of Sussex was there to show his support.
Well I don't know about you guys, but I'm cancelling all plans so I can watch Queen of the World, a new doco all about the British Royal Family that is set to premiere on United Kingdom telly station iTV next week. "It will keep us busy".
She's even won the favour of Queen Elizabeth II and has been seen on more than one occasion giggling alongside the 92-year-old when they've attended royal engagements together.
Then, as she touched her bespoke veil - which featured hand-embroidered flowers from each of the 53 Commonwealth counties - the Duchess exclaimed, "Fifty-three countries, oh my goodness".
Cape Town - Meghan (37) has done an exceptional job getting to know the royal family and the various protocols that come with them.
Meghan's husband Prince Harry also appears in the trailer for the documentary, in which he is seen joking that he still "panics" when he bumps into his grandmother the Queen in the corridors of Buckingham Palace.
The programme was filmed over more than a year, with special access to The Queen, her family, her staff and her homes.
"I know some have started eating - as you should, I'm the last one who'd want the food to get cold - so please enjoy a lovely lunch".
Queen of the World premieres September 25 on ITV and October 1 on HBO.
