It's A Girl! Kate Middleton Gives Birth To The New Royal Baby Girl

Britain has a new princess after Kate Middleton gave birth Saturday morning to a 8lb 3oz baby girl in London.

The Duke and Duchess of Cambridge's big news was announced on Twitter by Kensington Palace shortly after 11 a.m. BST a few hours after the delivery, which happened at 8:34 a.m. BST (3:34 a.m. ET).

The new baby girl is the fourth in line to the throne, behind Prince George who will turn two on July 22. Prince Harry has been pushed back into fifth place, while Prince Andrew — the Queen’s second son and the new child's great uncle — is now sixth in line.

Kensington Palace, which earlier tweeted that the Duchess had gone into labour, also gave some details about the new baby and the labour.

"The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news," the palace said in a statement emailed to media. "Her Royal Highness and her child are both doing well."

Following tradition, the announcement of the birth was placed on an easel in the forecourt of Buckingham Palace for the public to view — when George Alexander Louis, or Prince George of Cambridge, was born, people lined up to read the board.

The easel says: "Her Royal Highness The Duchess of Cambridge was safely delivered of a daughter at 8.34am today. Her Royal Highness and her child are both doing well."

It is likely to be a couple of days before we know the new baby’s name. In 2013, Kate and William made the announcement a day after the Duchess left hospital, which was two days after George was born — so the rampant speculation and betting will continue a little longer.
