LOS ANGELES (TND) — Jimmy Kimmel announced his 7-year-old son, Billy, is recovering after a third heart operation.

The late-night TV show host shared the news on social media Monday. The post included a photo of the boy smiling while laying in a hospital bed following the successful surgery.

This weekend, our boy Billy had his third (of three, we hope) open heart surgery," Kimmel wrote on Instagram. "We went into this experience with a lot of optimism and nearly as much fear and came out with a new valve inside a happy, healthy kid."

Kimmel said he and his wife, Molly McNearney, are grateful to his son's medical team at Children's Hospital Los Angeles (CHLA), adding that they "came through for us with immeasurable kindness and expertise." He also said spending time at the hospital and meeting other families was "a humbling experience."

We hope you never need CHLA, but if you do - know that they help families regardless of their ability to pay, thanks largely to the Affordable Care Act (another salute to the late Senator John McCain), generous donations from companies like Disney, which I am proud to work for and especially from generous people like you," he wrote.

He went on to thank fans for their love and support, as well as praised his loved ones, including Billy.

Thanks to those loving strangers who took time to pray for and send positive energy to our baby, thanks to our family and friends for rallying around us to an almost-ridiculous extent, thank you to my wife Molly for being stronger than is reasonable for any Mom to be and Billy, you are the toughest (and funniest) 7 year-old we know."

Kimmel has been open about his son's medical condition since the child's birth in 2017. He previously said his son was born with a heart defect and needed open-heart surgery when he was just three-days-old.

The child later had a second surgery in December of that year. Since then, Kimmel often shares health updates about his son and continues to call for health care reforms.

Kimmel is the host of ABC’s late-night host of "Jimmy Kimmel Live!" The show debuted in January 2003.
