Update: The early word on the royal baby's name is in, and she might be called Diana — sort of.

Original post: The Duke and Duchess of Cambridge are expecting a baby, the Royal Palace has confirmed, and apparently Kate already has some really terrible morning sickness. Here's the scoop (we'll add more to this as details come in): 

Us Weekly has now confirmed the pregnancy as well:

And ABC News has the official statement from the palace

Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting a baby... The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall and Prince Harry and members of both families are delighted with the news.

"The duchess was admitted to King Edward VII Hospital today in central London with hyperemesis gravidarum, an acute morning sickness which requires supplementary hydration and nutrients," reported ABC. 

Yes, that image above is Kate toasting with water in September. Back then, we noticed that a few photographers were focusing on Middleton's midsection and maybe-bump, and there were reports of her newly healthier drinking habits — she had toasted with water at a couple of state dinners instead of wine. 

If you're wondering what this child means for the monarchy, here's a simple explanation from People (which wrote this way back before any pregnancy) of why and how Kate and William's child could be a king or queen: 

Deputy Prime Minister Nick Clegg is exploring the idea of removing "male primogeniture," so the first-born boy in a family would no longer take precedence, even if he has an older sister

Regardless of primogeniture, this isn't good news for Harry (if Harry had any eyes on the throne) who will be bumped to fourth place by the new royal baby.
