After months of obsessive speculation, St. James Palace has confirmed the worst-kept secret in England: Kate Middleton is pregnant. That’s right, the Duke and Duchess of Cambridge are expecting their first baby, and while there was no word on whether they’re expecting a boy or a girl, the baby-betting bonanza has already begun. Paddy Power, Europe’s largest betting company, have bet on everything from the unborn child’s name to its hair color and godparents. Meanwhile, mum-to-be Kate has some serious morning sickness, and her currently nonexistent baby bump will likely be the most-covered topic in British tabloids until she gives birth. In honor of today’s joyous news, The Daily Beast looks at other royals with baby bumps and babies, from Princess Diana to Queen Elizabeth II.
