William and Kate waited four days to announce his name.

He is fifth in line to the British throne, after grandfather Prince Charles, father Prince William and his two older siblings, Prince George and Princess Charlotte.

On Friday, that announcement finally came via an official statement from Kensington Palace, which read, "The Duke and Duchess of Cambridge are delighted to announce that they have named their son Louis Arthur Charles".

Though some thought the name was ironic given that Louis was also the name 18 kings from across the Channel, it turns out that the name Louis holds a lot of significance in the Royal Family. He will also share the middle name of Arthur with his father.

Prince Louis' name (which means "renowned warrior" in French) may have been chosen to honor Prince Phillip.

Prince William and Princess Kate have announced the name of their third child: Louis Arthur Charles.

The Duke and Duchess of Cambridge's third child was born Monday at St. Mary's Hospital in London weighing 8 pounds, 7 ounces.

"It's unlikely they'll be asleep when William and Kate arrive home. I was so chuffed to see the baby's name.' And the links extend to Louis" sculptor dad Chris, 57, who created a pedestal for a bronze bust of the Queen which sits in Westminster Palace.

Mountbatten, who was known as "Dickie" by close friends, was the uncle of Prince Philip, 96, Queen Elizabeth II's husband, and great-grandfather of the new prince.

"The Duke of Cambridge is honoured to have been asked, and is very much looking forward to supporting his brother at St George's Chapel, Windsor on May 19th".

"Thrice the worry now", William told reporters, holding up three fingers with a smile, as he got into a Land Rover to take his wife and newborn back to Kensington Palace.

The name was a surprise, with the bookies' favorites having been Albert, Arthur, Alexander, James and Philip. Prince Charles was a month old before his name was made public.

It was signed today by Prince William.
