Shortly after the Twitter account of Clarence House, the royal couple's official residence, tweeted "Her Royal Highness The Duchess of Cambridge was safely delivered of a sun at 4:24 p.m.," Gov. Gen. David Johnston replied: "Wonderful news!"

Johnson tweeted that he and his wife, Sharon, are "overjoyed to learn that the royal couple are the proud parents of a baby boy."

The birth announcement, made via a press release from Kensington Palace, said Prince William's wife Kate gave birth to an 8 lb., 6 oz. baby boy at 4:24 p.m. London time. The infant will become third in line for the British throne after Prince Charles and his father William, the Duke of Cambridge.

The royal birth recalled that of the baby's father, William, in 1982, at the same central London hospital. Many remember the moment when he was carried out in his mother Princess Diana's arms with proud father Prince Charles at their side. Kate checked into a private wing at St. Mary's Hospital in central London early Monday morning. William spent the long hours of labor at her bedside, according to a statement
