The 69-year-old royal became a third-time granddad when his son Prince William and daughter-in-law Catherine, Duchess of Cambridge, welcomed their son - who is yet to have a name - into the world on Monday, and he has now expressed his "joy" at the news. As in the past, the Duchess had a quick labour and Prince Louis was born at 11.01 at 8lbs 7oz.
Footage of Kate Middleton has emerged which shows her revealing how we should really be pronouncing Prince Louis' name.
When Prince George and Princess Charlotte were born, the Duke of Cambridge was working as a RAF helicopter pilot, and air ambulance helicopter pilot respectively. The Duchess of Cambridge is expected to return to her royal duties in the fall as she takes time to care for her family.
Alongside shy older brother Prince George, it was Charlotte who waved to photographers as she led her father the Duke of Cambridge up the steps of the Lindo Wing. Unlike his siblings Prince George, 4, and Princess Charlotte, 2, Louis' birth certificate is typed and not handwritten.More news: Opportunistic Jets Steal Game 1 From Preds
The young princess began nursery, starting at Willcocks Nursery School close to her Kensington Palace home.

"It has been a great honor to register and formally welcome the latest addition to the royal family, Prince Louis Arthur Charles", Gordon said in a statement.
The baby is Britain's first Prince Louis in more than a century. The document for Prince William and Kate Middleton's third child was released on Tuesday, May 1, and there are some details on the piece of paper that we can't help but laugh about. The Duke signed the registry at Kensington Palace overseen by a registrar from Westminster Register Office. His middle name Charles, of course, comes from his paternal grandfather, The Prince of Wales.
