The baby will be the second for the comedian and his wife, who welcomed daughter Jane in 2014. Kimmel also has two children, Kevin and Katherine, from a previous marriage.
The Live! host said that he and McNearney don’t yet know if they’re having a boy or a girl, joking that the couple plan to “let the child decide for itself.”
“We want it to be a surprise, but I have been trying to think of names that would work for either a boy or a girl,” he added. “So far I've come up with two. Number one, Dyson, after the vacuum. Or ‘Jelatin,’ with a J. No? That's exactly what my wife said.”
2017 is shaping up to be a big year for Kimmel! Check out some of the highlights from his hosting turn at this year’s Emmys in the video below.
