Jimmy Kimmel isn’t just the hilarious host of Jimmy Kimmel Live! — he’s now a proud grandfather at 57! While fans were shocked to hear the news, Kimmel’s personal life continues to surprise with more than a few surprises up his sleeve. Let’s dive into his journey from father to grandfather.
In May 2025, Kimmel had to take an unexpected night off from his late-night show. It turns out the reason was heartwarming: his oldest daughter, Katie Kimmel, had just welcomed a baby girl — making Jimmy Kimmel a proud grandfather for the first time.
Kimmel, known for his quick wit and humor, joked about his daughter’s age during the reveal, quipping, “My daughter had a baby last night. People don’t realize I have two little kids, but I also have two older kids. My oldest daughter, she’s 83 years old, her name is Katie.”
Of course, Kimmel was just being his usual self — his daughter Katie is 33, and his son Kevin is 31. But the surprise for most of his fans was the fact that Jimmy’s grandchild had arrived — and nobody saw it coming.
Kimmel revealed his granddaughter’s name: Patti Joan. The middle name “Joan” was a tribute to his own mother, Joan Kimmel. He went on to share, “The baby is healthy, and they gave her a very cute name…Her name is Patti.” 
A Grandfather’s Life, But With a Comedic Twist
When asked on his show how it feels to be a grandfather, Kimmel laughed and admitted that it was easier than being a dad. In a hilarious exchange with Thor actor Tom Hiddleston, Kimmel jokingly said, “There’s definitely a ranking in my head. That’s my granddaughter’s decision to make, but trust me, I will do all I can to be numero uno.”
Kimmel’s quick wit has kept fans laughing through the years, and now his fun-loving personality shines in his new role as a doting granddad.
What About His Older Kids?
While many fans know about his two younger children with his wife Molly McNearney, Kimmel’s older kids from his first marriage to Gina Maddy — Katie and Kevin — tend to fly under the radar. Jimmy often jokes about their age differences and admits many fans forget about his grown children.
Will Grandfatherhood Change Jimmy Kimmel?
Fans are left wondering if this new chapter in Kimmel’s life will influence his career or just bring more humor to his family-oriented persona. Will he compete with other grandparents for the title of “Best Grandpa”? Only time will tell!
