PRINCE George is set to be our future King and is the heir to the throne.
He is the eldest child of Prince William and Kate Middleton and is second-in-line to the throne. Here's what you need to know about the young prince.
What is Prince George's full name?
Prince George's full name is George Alexander Louis.
It took his parents, the Prince and Princess of Wales, two days to announce his name.
It was announced in a statement by the Royal Family at the time, which said: "The Duke and Duchess of Cambridge are delighted to announce that they have named their son George Alexander Louis.
"The baby will be known as His Royal Highness Prince George of Cambridge."
What’s his full title?
His full title is His Royal Highness Prince George of Wales.
The "Wales" surname came into effect after his parents Prince William and Kate Middleton were given the titles Prince and Princess of Wales, when Charles III became King.
Where does George Alexander Louis come from?
It is thought the name George was given in homage to Prince William’s great-grandfather King George VI.
The Queen’s father, born Albert Frederick Arthur George, was known as Albert publicly and Bertie among friends.
He selected the name George as his regnal name, in part to emphasise continuity with his father, King George V.
The name Alexander is thought to pay tribute to the late Queen, whose middle name was Alexandra.
Louis is one of his dad Prince William's middle names, with his full name being William Arthur Philip Louis.
It is also thought to be a nod to Louis Mountbatten, Prince Philip's uncle.
Also a second cousin once removed of Queen Elizabeth II, he is said to have been close to his nephew.
His full title was Louis Francis Albert Victor Nicholas Mountbatten, 1st Earl Mountbatten of Burma.
How much older is he than his little brother?
Prince George was born on July 22, 2013, and Prince Louis was born on April 27, 2018.
That means there is 1,741 days between the brothers, if you count the day the new prince was born.
That translates into four years, nine months and six days.
George is 650 days older than his little sister Charlotte, who was born on May 2, 2015.
Counting the day she was born, it means Prince George is one year, nine months and 11 days older than Princess Charlotte.
And she herself is 730 days older than her little brother Louis, including the day he was born.
There is one year, 11 months and 30 days between the two youngest children.
