The pictures selected by both couples show Meghan at the Queen's Service of Thanksgiving at St Paul's Cathedral during the monarch's Platinum Jubilee celebrations.
The service was the only event from the Queen's Jubilee which the Duke and Duchess of Sussex publicly attended, after they returned to the UK from California for the occasion.
Meanwhile, it was recently revealed that Omid Scobie is writing a new book about the couple.
The London-based author previously teamed up with Carolyn Durand on 2020 biography Finding Freedom: Harry and Meghan and the Making of A Modern Royal Family - for which the duchess confirmed she gave her permission for a friend to be interviewed - but he's now going it alone to pen a "new chapter of the royal story".
According to the Mail on Sunday newspaper's Emily Prescott, the book will share some "exclusive revelations" about Harry and Meghan and the author has promised "deep access" to the couple and their associates.
