A baby boy was born to Catherine, the Duchess of Cambridge and Prince William at 4:24 p.m. GMT (11:24 a.m. ET) Monday. The baby weighed 8 pounds, 6 ounces at birth.
The baby was born in the Lindo Wing of St Mary’s Hospital in London, where William and Harry were both born.
Kate delivered naturally and the labor was overseen by Alan Farthing, the queen’s surgeon-gynaecologist.
In a break with tradition, the birth was initially announced via an emailed press release as opposed to a notice posted to an easel at the gates of Buckingham Palace.
"William and Kate's officials say they've made this change so the birth announcement can be made as 'quickly and simply as possible,'" the BBC's Peter Hunt reported.
The press release did not reveal the child's names (yes, names), instead stating that they would be announced "in due course." It also reiterated the infant's title: "His Royal Highness Prince [NAME] of Cambridge."
After the announcement had been made, the official proclamation was framed and taken to be displayed at Buckingham Palace.
Her Royal Highness the Duchess of Cambridge was safely delivered of a son at 4:24 p.m. today.
Her Royal Highness and her child are both doing well.
The little prince will be third in line to the throne, after his father and grandfather, Prince Charles.
Clarence House confirmed the news via Twitter.
Prince Charles released a very sweet message shortly afterward:
Both my wife and I are overjoyed at the arrival of my first grandchild. It is an incredibly special moment for William and Catherine and we are so thrilled for them on the birth of their baby boy.
Grandparenthood is a unique moment in anyone's life, as countless kind people have told me in recent months, so I am enormously proud and happy to be a grandfather for the first time and we are eagerly looking forward to seeing the baby in the near future.
The Royal Family's official Twitter account posted a message from the Queen and Prince Phillip, the child's great-grandparents.
Per tradition, a Town Crier proclaimed the news outside the hospital.
The new family will live in Kensington Palace in the recently renovated apartment 1A.
"We could not be happier," Prince William said in a statement Monday night.
The news was met with great excitement in London.
Thousands of people swarmed Buckingham Palace to see the royal proclamation.
President Obama and First Lady Michelle Obama released a statement congratulating the proud parents:
Michelle and I are so pleased to congratulate The Duke and Duchess of Cambridge on the joyous occasion of the birth of their first child. We wish them all the happiness and blessings parenthood brings. The child enters the world at a time of promise and opportunity for our two nations. Given the special relationship between us, the American people are pleased to join with the people of the United Kingdom as they celebrate the birth of the young prince.
The First Lady also tweeted a personal message to the couple.
