Find out how much he got paid for the hosting gig.

Jimmy Kimmel’s son is finally home after a terrifying experience.

During his opening monologue on Monday (May 1, 2017), the late night talk show host revealed his newborn, William “Billy” John Kimmel, recently underwent open heart surgery to correct a heart murmur. According to the comedian, doctors diagnosed the baby boy with “tetralogy of fallot with pulmonary atresia” — a blockage in the pulmonary valve with a  hole in the heart wall — just three hours after his birth on April 21.

“On Monday morning, Dr. [Vaughn] Starnes opened his chest and fixed one of the two defects in his heart. He went in there with a scalpel and did some kind of magic that I couldn’t even begin to explain,” Kimmel said as he teared up. “He opened the valve, and the operation was a success. It was the longest three hours of my life.”

“He’ll have to have another open heart surgery in three to six months,” he continued. “He’ll have a third — hopefully non-invasive — procedure some time maybe in his early teens.”

The 49-year-old and his wife, writer Molly McNearney, were brought Billy home the past weekend.

“Poor kid. Not only did he get a bad heart, but he’s got my face,” Kimmel joked. “He’s doing great. He’s eating. He’s sleeping. He peed on his mother today while she was changing his diaper. He’s doing all the things that he’s supposed to do.”

Kimmel and McNearney are also parents to 2-year-old daughter Jane.
