The Princess of Wales has taken on a number of different titles since joining the royal family. When it was publicly confirmed that she was dating Prince William in 2004, she was often referred to as Kate or Kate Middleton by the British public, and ahead of her wedding to William in 2011 she was increasingly styled as Catherine. After tying the knot, the couple were given the Duke and Duchess of Cambridge titles from the late Queen Elizabeth II as a wedding gift, and upon the monarch's death in 2022 they were passed the Prince and Princess of Wales titles.
Across the world, the future Queen consort is still known as Kate, Kate Middleton or Princess Kate, but the royal family refer to her as Catherine in an official capacity. She also reportedly emailed friends when her relationship with William started to get serious, asking them to start using Catherine, too.
