VIDEO : Jimmy Kimmel Shares Positive Health Update on Newborn Son's Heart Condition

Jimmy Kimmel is giving thanks after the birth of his son, Billy Kimmel. The late-night host took to Twitter with a hopeful message, one day after informing viewers his second child with wife Molly McNearney was born with a health condition that required open heart surgery. During Kimmel's emotional opening monologue, he revealed that three hours after Billy was born, doctors at Children's Hospital Los Angeles noticed something wasn't quite right. Kimmel explained about the surgery and the heart condition saying, "(the Doctor) opened the valve, and the operation was a success. It was the longest three hours of my life." Jimmy and Molly's baby has since left the hospital and is adjusting to life at home.
