Jimmy Kimmel Reflects on Son Billy’s Health Scare in Tribute Post

He also shared a similar message of appreciation to the doctors and nurses who took care of Billy on the child’s fourth birthday, noting he’s “doing great.”

“He’s really a fun, normal little kid,” Kimmel, who also shares 7-year-old daughter Jane with McNearney, and kids Katie, 30, and Kevin, 28, with his ex-wife Gina Kimmel, told E! News in 2019. “He’s very into Spider-Man. He calls Spider-Man ‘Fighter Man’, which might be a new hero. But he runs around in a little Spider-Man costume and its got muscles on it and it’s weird because it looks like a tiny little adult has invaded our home.”

Over the years, fans have seen Billy make a number of cameos on his dad’s show, playing rounds of “Who Wants to Be a Millionaire?,” appearing in a clip on how to behave in the workplace and meeting Spider-Man‘s Tom Holland.

Happy birthday, Billy!
