Buckingham Palace has confirmed that the princess is just pass her first trimester and has been having lots and lots of morning sickness (princess or not, that baby doesn't care)
This is the statement from the official Royal website:)
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 this afternoon to King Edward VII Hospital in Central London with Hyperemesis Gravidarum. As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter.
Wait..she wasn't in Vegas at the same time as Prince Harry, was she?
