This is McNearney's first child and Kimmel's third. The Jimmy Kimmel Live host has two kids, Kevin, 20, and Katie, 22, from his first marriage. Kimmel and McNearney, the co-head writer of his late-night show, married in July 2013 after four years together.
"I've really forgotten everything. It's funny because I was with [John Krasinski and Emily Blunt], who just had a baby and I was like, 'Oh yeah, and there's new ways to do things,'" Kimmel, 46, told DeGeneres of raising children. "I told my daughter, 'Listen, there's only so much love I have to give — you're going to have to split it up with the new kid. There's a finite amount of love and that's that.' So they're dealing with it, but it is very weird at my age. I'm going to be one of those old dads."
