Jimmy Kimmel’s son Billy is continuing on the road to recovery.

The Who Wants To Be a Millionaire presenter revealed that his 7-year-old son, who was born with a congenital heart defect, is back to his normal self after undergoing his third open-heart surgery in May.

"Billy's doing great. He had open-heart surgery, you know, he's got the scars and everything, but he's just mentally right back where he was, which is crazy,” Kimmel told Entertainment Tonight. “Physically, you know, we're gonna have to be careful with him for a couple of months, but he's doing really well.”

The late-night host also expressed his amazement over how incredibly resilient children are. “They're made of rubber,” he said. “Everybody says that kids are so resilient, and the doctors actually explained it to me, which, I don't know why it never occurred to me before, because they're still growing and we’re not. Ideally, we’re not. We’re shrinking.”

Billy was born with Tetralogy of Fallot with VSD, a rare congenital heart defect that required him to have open-heart surgery at just three days old. He continues to receive treatment for the condition.

In a May Instagram post, Kimmel confirmed that Billy had completed his third — and hopefully final — open-heart surgery, which saw a surgeon insert a new valve in his heart. The comedian praised his son, calling him "the toughest (and funniest) 7-year-old we know," and thanked the staff at Children’s Hospital Los Angeles for coming “through for us with immeasurable kindness and expertise” during his stay.

Kimmel concluded his note by encouraging his followers to donate to either Children's Hospital Los Angeles or their own local children’s hospital, adding, "Nothing matters more than taking care of each other."

Shortly after Billy's birth, Kimmel returned to television to give an emotional speech about the importance healthcare reform in the United States. "No parent should ever have to decide if they can afford to save their child’s life," he said. "It just shouldn’t happen. Not here.”
