Jimmy Kimmel has said his son Billy is “healthy and happy” following his battle with a congenital heart defect.

The 49-year-old talk show host and his wife Molly McNearney welcomed their second child into the world six months ago, and were devastated to learn he had to undergo life-saving heart surgery after doctors discovered he had a congenital heart defect.

But Jimmy – who also has three-year-old Jane with his spouse, as well as daughter Katie, 26, and son Kevin, 23, with his former wife Gina – has now shared an adorable photo of Billy to celebrate him turning six months old, and has revealed the tot is doing well following his surgery.

The ‘Jimmy Kimmel Live!’ host wrote on social media: “Young Billy is six months old today. He is healthy and happy and we are all very grateful for your prayers, good wishes, thoughts and support of @ChildrensLA and children’s hospitals in your area. (sic)”

It isn’t the first health update Jimmy has given surrounding his son either, as he recently joked that the tot was doing amazing things beyond his age such as “juggling”.

He said: “He’s doing great. Young Billy made his first visit to our office today. He’s juggling. He’s translating Flaubert from French into English. He’s really an amazing kid. No – he smiles. That’s pretty much it. He is very interested in ceiling fans. He likes those a lot. I could get him to pay the same amount for Netflix just to watch ceiling fans.”

And Jimmy also shared another update last month, where he said his son was “doing well”.

He said: “Billy is doing well. He’s right there! He’s got to have another operation soon, but he’s doing well. He seems to be strong. He pulls hair, that’s for sure!”

Billy has to undergo two more surgeries in the coming months, and Jimmy has admitted he’s nervous for the procedures and wants to get them “over with”.

He added: “He has to have two more open heart surgeries. We would like to get them over with and not have to think about it all the time, but it could definitely be worse.”
