The royal baby boy has been born!
The Queen's Press Secretary and a footman posted the official announcement of the birth of The Duke and Duchess of Cambridge's baby in Buckingham Palace forecourt.
It read: "Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 4.24 p.m. The baby weighs 8 pounds 6 ounces. Her Royal Highness and her child are both doing well."
The announcement had the official Buckingham Palace heading and the signatures of the medical staff who helped deliver the newborn.
Kate and Wills have yet to release their son's name, but he will be addressed as the Prince of Cambridge, a title that has not been used in over 190 years.
Middleton arrived at the hospital at 6 a.m. local time after going into labor. She was joined by her hubby, who was by her side for every step of the way. The two entered the hospital through a side door and were driven from Kensington Palace via a two-car convoy.
