Prince William and Kate Middleton just quietly changed their titles

Yet, it can only be passed down to the first male heir, meaning Prince George is likely to inherit the title once Prince William becomes King William.

In addition to the Duke and Duchess of Rothesay, they’re also known as the Duke and Duchess of Cornwall and Earl and Countess of Chester.

At some point, they’ll also be known as King and Queen, so they’d better not get too attached to their current titles or dare to personalise items with the Duke and Duchess monikers.
