The couple's child will have a unique moniker
Kate and William‘s formal names are the Duke and Duchess of Cambridge and their little one – who’s due on Saturday – will follow suit when it’s born.
‘The royal couple’s child will officially be known as His or Her Royal Highness the Prince or Princess of Cambridge,’ says a palace spokesman.
Kate, 31, is expected to give birth naturally at London’s St Mary’s Hospital, where William, also 31, arrived in 1982.
The pair’s boy or girl will be the first person ever to have its moniker.
‘We did a lot of research,’ former Cambridge mayor Sheila Stuart tells The Sun.
‘There were some dukes of Cambridge but not a prince or a princess.’
