She's pregnant!  Kate Middleton, the Duchess of Cambridge, is officially going to be a mum.

People.com reports a royal offspring is on the way for Kate and Prince William.  The first for the couple who wed in April of 2011.

The royal palace confirmed the news via a statement Monday.

"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 statement goes on to say:

"The Duchess was admitted 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."

How does this pregnancy effect the monarchy at Buckingham Palace?  Well, even if William and Kate's baby is a girl, she can expect to inherit the throne from her father, regardless of whether any other child the royal couple has is a boy. Until a recent rule change, a male heir historically took precedence.

The growing family will have a wonderful palace home to move to when the baby is growing up. The couple is expected to relocate to the 20-room Apartment 1A at Kensington Palace early next year.
