(LONDON) - Palace officials say Prince William and the former Kate Middleton's first baby is due in July and that her condition is improving.
The Duchess of Cambridge, as she is formally known, had been hospitalized earlier in her pregnancy for acute morning sickness.
Officials said Monday she is feeling better. She made a rare public appearance last week and appeared to be healthy.
The infant would be third in line for the British throne.
The announcement by the couple's St. James's Palace office lays to rest speculation that the duchess could be having twins.
The palace would not comment on whether the baby is a boy or a girl. The British government is changing centuries-old succession laws to ensure that a royal daughter will have the same claim to the throne as a son.
