The Duke of Sussex is sixth in line to be king after his nephew Prince Louis, the son of Prince William.
The Duke and Duchess of Sussex have always been close with the princess and her husband even during their dating days.
The Duchess of Cambridge shared that she would tell her husband "let's have another one" each time she meets under-one-year olds.
The Duchess of Sussex was able to "generate the kind of support that no other member of the Royal Family has been able to generate."
Buckingham Palace announced that the British monarch will continue to do light duties from her desk amid her COVID-19 battle.
Her Majesty is worried that the Duke of Sussex will call his father "not worthy of being future king" in his book.
"You won't meet nicer or more genuine people" and "this must be an agonisingly difficult time for them."
