The Duke and Duchess of Cambridge are expecting their third baby in spring next year.
Kensington Palace have confirmed the Royal baby will be born in April.
A palace statement said: 'Their Royal Highnesses The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in April 2018.'
Kate will be well into her pregnancy when the Royal couple make an official visit to Norway and Sweden early next year.
She was hailed a 'fighter' after attending a reception in Buckingham Palace to honour mental health campaigners whilst herself battling hyperemesis gravidarum - a severe form of morning sickness.
But it did not stop her from making a surprise appearance at a royal engagement on Monday.
She took a twirl with Paddington Bear as they danced on the platform of Paddington Station, watched by William and Prince Harry, at a charity event.
