"Their Royal Highnesses The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in July," read the simple statement, released by the Palace at 11 a.m. London time.
"The Duchess's condition continues to improve since her stay in hospital last month," the statement also said. Kate sought treatment in early December for severe morning sickness.
A Palace source confirms Kate is not expecting twins. The source adds that the couple will not be revealing the sex of the baby.
A July arrival would allow the baby to share the same birth month as William's late mother Diana, Princess of Wales, who was born on July 1.
Insiders say that the timing of the announcement means they have likely had their scans to show that the pregnancy is going according to plan. There is clear relief around the Palace that they have been able to release the news.
"Happy days," said a source.
