Talk show host Jimmy Kimmel has shared a heartwarming update on his son, two years after his life-saving heart surgery.
Kimmel's son William "Billy" John, who turned two in April, is now "doing great", according to the comedian.
"He thinks he's Spider Man now, so we're safe from crime," the Jimmy Kimmel Live! host told Us Weekly.
"He wears the costume all the time. He's shooting webs all over the house.
"He goes to preschool as his secret identity and then turns into Spider Man when he comes home."
Billy, was born with a congenital heart defect called Tetralogy of Fallot with pulmonary astresia. It meant his pulmonary valve was blocked and there was a hole in his heart.
As a result, he needed emergency open-heart surgery shortly after his birth in 2017.
At the time, Kimmel gave a stirring monologue on his show urging sweeping changes to America's health system, while emotionally recounting his son's heart problems.
"On Monday morning, Dr. Vaughn Starnes opened his chest and fixed one of the two defects in his heart," Kimmel said. "He went in there with a scalpel and did some kind of magic that I couldn't even begin to explain. He opened the valve, and the operation was a success."
"It was the longest three hours of my life."
The operation was a success and his son's recovery was smooth.
"He's doing great. He's eating. He's sleeping," he said.
"He peed on his mother today while she was changing his diaper. He's doing all the things that he's supposed to do. This is the best."
He has since had another surgery on his heart and will need one more in his teens.
When his son is old enough to ask about his scar, Kimmel said they have a plan in place.
"You'd have no idea (anything was wrong) besides his awesome scar on his body," he said.
"We're going to tell him he was attacked by a monster."
In April, he shared a photo of Billy on his second birthday and thanked the hospital again for saving his life.
"Happy 2nd birthday to our little Easter buddy Billy," he wrote.
He also has a five-year-old daughter Jane with his wife Molly McNearney and two other children Katie, 28, and Kevin, 25, from a previous marriage.
