Catherine, Duchess of Cambridge — better known as Kate Middleton — became the subject of much fascination in the UK press when she began dating Prince William in the early 2000s. Royal watchers the world over were eager to learn more about the beautiful young woman who might one day marry the future king. When William proposed, Middleton-mania went into overdrive, and since then, the mother of two (that number will increase to three in 2018) has wowed the world with her grace, elegance, and modern approach to royal protocol.
