Catherine is suffering from acute morning sickness and is being attended to by doctors at their official royal quarters at Kensington Palace.

The new baby will be fourth in line to the crown, after Prince Charles, Prince Williams and Prince George.

The baby announcement comes just two months after Prince George celebrated his first birthday.

The Duchess will be restricting her royal appearances at the moment due to her morning sickness and all future official outings will be decided on a case to case basis, reports the BBC.
