Like Kate Middleton, she will not become a princess after marrying one of Princess Diana’s sons. Following in the Duchess of Cambridge's footsteps, the 36-year-old will become HRH the Duchess of Sussex.
When Middleton married Prince William in 2011, Queen Elizabeth gave them the royal titles of the Duke and Duchess of Cambridge. As the next in line to the throne, William will likely become the Prince of Wales when his dad, Prince Charles, becomes the King of England. Harry is sixth in line to the throne after William and Kate’s children Prince George, Louis and Princess Charlotte.
