Jimmy Kimmel‘s baby boy is a fighter.
“Billy is three months old today and doing great,” the Jimmy Kimmel Live host wrote on social media. “Thanks for all your love & support and please remind your Congresspeople that every kid deserves the care Billy got.”
Alongside the note, Kimmel shared a photo of his smiley son.
Billy was born with a congenital heart disease, Kimmel, 49, revealed in a tearful monologue on his show back in May.
Kimmel’s wife Molly McNearney gave birth to William John “Billy” Kimmel on April 21. At 3 days old, Billy underwent the surgery at Children’s Hospital Los Angeles because of his condition, the tetralogy of Fallot with pulmonary atresia.
“Basically, the pulmonary valve was completely blocked and he has a hole in the wall between the left and right sides of his heart,” Kimmel previously explained, adding that despite the successful open heart surgery, Billy will have another operation between 3 and 6 months old.
Joked the star, “Poor kid. Not only did he get a bad heart, he got my face.”

Kimmel and McNearney also share a 3-year-old daughter, Jane. The host has two older children – Kevin and Katie – from a previous relationship.
