Jimmy Kimmel has officially joined the “Grandparent Club” after his daughter, Katie Kimmel, gave birth to a baby girl named Patti Joan on May 19, 2025. The announcement came during the May 20 episode of Jimmy Kimmel Live!, following his rare absence from the previous night’s show to be with his family at the hospital—a decision he humorously explained was due to the birth of his first grandchild .

Katie, 33, is Kimmel’s eldest child from his first marriage to Gina Maddy. She and her husband, Will Logsdon, welcomed their daughter, who is named in part after Kimmel’s mother, Joan . Kimmel shared that his granddaughter’s middle name, Joan, honors his late mother, reflecting a heartfelt tribute to his family .(People.com)

This milestone marks only the second time in Kimmel’s 22-year late-night career that he has missed a show, the first being in 2007 due to an emergency appendectomy .
