In case you missed it, Prince Harry and Meghan Markle are engaged! The two will be wed sometime in Spring 2018 but now the question is, what will Markle's title be? Well, because she currently has no other titles, once the two marry her formal title will be 'Her Royal Highness Princess Henry of Wales.' She may also get another title, depending on if Prince Henry becomes the Duke of a province, like his brother did with his marriage. If that happens, Markle will then become a Duchess. Not too shabby for a girl from Los Angeles.
