Prince William and Kate have named their new-born baby boy, George Alexander Louis, William's office said today. The baby is Britain's third-in-line to the throne.
"The Duke and Duchess of Cambridge are delighted to announce that they have named their son George Alexander Louis," a statement from the palace said.
"The baby will be known as His Royal Highness Prince George of Cambridge."
Kate gave birth to a baby boy weighing 8 lbs 6 oz (3.8 kg) two days ago, announced officially via a notice pinned to an easel outside of Buckingham Palace.
Six King Georges have worn the crown throughout history since the German-born George I, the first Hanoverian king of Great Britain, acceded to the throne in 1714.
The last was the Queen's father George VI who died in 1952 but was known to his family as Bertie.
George was the most popular name with the bookies with betting firms offering short odds on the moniker.
The name Louis is likely to be a tribute to Lord Louis Mountbatten, the Duke of Edinburgh's uncle and the last British Viceroy of India before independence in 1947.
Mountbatten and William's father the Prince of Wales were very close, with Charles confiding in his relative.
He was known by the royal family as Uncle Dickie and was assassinated by the IRA in August 1979.
His boat was blown up on a fishing trip off the coast of County Sligo, Republic of Ireland.
