Kate Middleton is officially one of the "beautiful people." Her place was confirmed by a poll on the dating website BeautifulPeople.com, which surveyed no less than 127,000 responders to judge the prettiness of the princesses.

The princess bride, who becomes British royalty when she marries Prince William, came in a notable third out of the 10 most beautiful royals in history. She placed ahead of her future husband's mother, the late Diana, princess of Wales, who ranked fourth.

Topping the poll: the iconic beauty Princess Grace of Monaco. The Oscar-winning American actress Grace Kelly was Hollywood royalty before before marrying Prince Rainier in 1956. Coming in a close second, the stunning Queen Rania of Jordan.
