Catherine, Duchess of Cambridge, gave birth to a baby boy on Monday morning, according to Kensington Palace, touching off widespread jubilation across Britain. Her husband, Prince William, 35, was by her side for the birth of their third child.
“The baby weighed 8lbs 7oz,” Kensington Palace said in a tweet.
“The Duke of Cambridge was present for the birth. Her Royal Highness and her child are both doing well.”
According to tradition, news of the birth was later displayed on an easel in front of Buckingham Palace.
British Prime Minister Theresa May offered her “warmest congratulations” and wished them “great happiness for the future.”
Minutes after the birth, Britons began to joke that Will and Kate, as the couple are informally known, will now have a palace filled with heirs and spares'.
The soon-to-named babe is fifth in line for the throne — not a bad resume for his first day on the job.
