We have been hearing an exhaustive set of baby rumors since the couple got married in April 2011 but this time it is official.
Kate was diagnosed with hyperemesis gravidarum, a severe form of morning sickness that affects one in 50 women — and occurs more often when moms-to-be are expecting twins.
So it is possible that the royal couple may be having twins.
Here is the official Statement of Kate Middleton’s pregnancy which is just released by palace officials.
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.
