Joy at the news of the birth of a future King dominates the front pages with The Sun marking the event with a change of masthead from The Sun to The Son.
The front page of the newspaper was filled almost entirely with the statement on Buckingham Palace headed notepaper confirming the royal birth and placed last night on an easel in the forecourt of Buckingham Palace.
At the bottom of the page, the news was summed up in just three sentences: "At 4.24pm yesterday, an 8lbs 6oz baby boy was born at St Mary's Hospital, London. To William and Kate, a son. To the nation, our future King. Let the celebrations begin!"
And in America...
A number of other newspapers opted simply for the headline "It's a Boy" - chosen by The Daily Telegraph, the Daily Star and the Daily Express.
The Times declares: "A Prince is Born" while The Guardian marks the occasion with the headline "A Birth, a boy, a prince a king."
The Mirror front page is filled with a Mario Testino photograph taken to mark the engagement of the Duke and Duchess of Cambridge along with an inset picture of the easel at Buckingham Palace with the headline "Our Little Prince".
The Daily Mail takes a playful approach, featuring a picture of a thrilled-looking Prince of Wales in Yorkshire after hearing the news of the birth with the headline "Oh boy! One's a grandpa."
