Prince Harry, Meghan Markle to join Prince William, Kate for final royal engagement

The Fab Four are getting back together.

It's been announced Prince Harry and Meghan Markle's final royal engagement before the pair leave their duties behind for financial independence and life across the pond in Canada will be alongside Prince William and Kate Middleton. 

The four will join the Queen, Prince Charles, and Camilla at a Commonwealth service at Westminster Abbey on March 9. It will be the first time the royal renegades have been in public with their family since announcing their intention to leave their royal duties and move to North America.

However, there will be one famous face missing. According to The Sunday Times, Archie, Meghan and Harry's son, won't be returning to the United Kingdom for the goodbyes. He has been in Canada since November. That has reportedly upset the Queen, who is understood to be "very sad" she has seen little of the young child since his birth last year.

When Harry and Meghan first began dating and became married, they were known along with William and Kate as the Fab Four. However, a rift between the two couples soon emerged and they have rarely been seen together over the last year.

The Duke and Duchess of Sussex will officially become independent on March 31, with the pair's office at Buckingham Palace being closed on April 1. They will no longer be able to use the 'Royal' brand either. 

Following talks at Sandringham Estate in January, Queen Elizabeth said while she wanted the pair to stay full-time royals, she understood their desire to live an independent life. 

"My family and I are entirely supportive of Harry and Meghan's desire to create a new life as a young family.

"Although we would have preferred them to remain full-time working members of the royal family, we respect and understand their wish to live a more independent life as a family while remaining a valued part of my family."

It has been reported that Meghan has signed a deal with Disney and is also in talks with multiple fashion houses, potentially signalling how the pair will support themselves.
