His Royal Highness The Duke of Cambridge and Her Royal Highness The Duchess of Cambridge
The Kate Middleton is no longer just Kate. Nor Prince William is just William. They have new royal titles.
After they exchanged vows morning at the Royal Wedding, the two will officially be known as the Duke and Duchess of Cambridge.
“The Queen has today been pleased to confer a Dukedom on Prince William of Wales. His titles will be Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus. Prince William thus becomes His Royal Highness The Duke of Cambridge, and Miss Catherine Middleton on marriage will become Her Royal Highness The Duchess of Cambridge”, Queen Elizabeth II’s press secretary said.
