A new reign has begun following the passing of Her Majesty Queen Elizabeth II.
With King Charles III taking over the crown as Britain's latest monarch, his eldest son, Prince William (Duke of Cambridge) is now the heir apparent to the throne- making him and his wife the new Duke and Duchess of Cornwall.
The royals have since updated their official social media handles (Twitter, Instagram) with the newly-bestowed titles.
Following the revelation, they are also slated to inherit the titles of Prince and Princess of Wales, having previously held by King Charles III until the Queen's death.
