Jimmy Kimmel's son Billy made a TV debut on Monday, December 11 episode of "Jimmy Kimmel Live!". The episode marked Jimmy's emotional return after he was forced to temporarily hand over his hosting duty to a slew of celebrity guest hosts, including Chris Pratt, Jennifer Lawrence, Melissa McCarthy and Channing Tatum, following the 7-month-old baby's second heart surgery.

"I was out last week - because this guy had heart surgery. But look, he's fine everybody, he may have pooped but he's fine," the Oscar-winning host, who had Billy on his arms, told viewers while holding back tears during his monologue. "Daddy cries on TV but Billy doesn't… it's unbelievable."

"Billy is doing great, by the way. He has one more surgery - this is amazing - he had an operation a week ago," he later added. "They say he'll probably on track to win at least a bronze medal at the Olympics in 2036."

Jimmy also expressed his gratitude towards "the bright and talented doctors and nurses at Children's Hospital who treated Billy, and not just Billy, [but] many kids with so much caring and compassion." The host also addressed an issue about CHIP (Children's Health Insurance Program) which is at risk of being defunded. The host encouraged viewers to call the House and Senate at (202) 225-3121 to tell them to fully fund CHIP, which was created in 1997.

Jimmy and wife Molly McNearney welcomed Billy on April 21. Born with a rare congenital heart defect, Billy had to undergo a surgery three days after he was born. Jimmy and Molly also share 3-year-old daughter Jane, while Jimmy has two older children, Kevin and Katie, from a previous relationship.
