Prince Charles is thrilled to have a royal grandson after his daughter-in-law Kate Middleton gave birth to a healthy baby boy on Monday at 4:24 p.m. London time.

The Prince of Wales, who became a grandfather for the first time on Monday, said he was “enormously proud and happy,” the Daily Mail reported. He said: “Both my wife and I are overjoyed at the arrival of my first grandchild.”

Though he didn’t let the royal baby’s birth hinder his royal duties (he went on a scheduled visit to York), Charles couldn’t help but be overjoyed after the child’s arrival.

“It is an incredibly special moment for William and Catherine and we are so thrilled for them on the birth of their baby boy,” the prince continued.

“Grandparenthood is a unique moment in anyone’s life, as countless kind people have told me in recent months, so I am enormously proud and happy to be a grandfather for the first time and we are eagerly looking forward to seeing the baby in the near future.”

Earlier in the day, when asked in York if he had any news regarding the royal baby, Charles reportedly quipped, “No. You'll hear before I do, I suspect.”

One of the hottest topics surrounding the child’s birth is his name. As expected, the royal baby’s name is yet to be announced. It’s widely believed he will be named George, but the baby’s parents have remained mum on the subject. For those who are eager to find out the prince’s moniker, they could wait as long as a month. It took Queen Elizabeth II and Prince Phillip that long to name Prince Charles. If he’s just like dad, it will be two weeks before the public knows what to call the royal baby.
