The big reveal happened during Monday's taping of Kimmel's late-night show, the Daily Mail reports. Naturally, the proud dad devoted his monologue to life with Jane, starting with her July 10 delivery. "My wife is doing fine, I'm fine too," he told the audience. "I was so brave. I cried a little but I didn't scream. You guys would've been very, very proud of me."
The third-time dad -- he has two older children from his first marriage -- is clearly smitten with his baby girl. Explaining that he's taking "somewhere in the neighborhood of 10,000 pictures of her a day," he joked that Jane has finally had enough. "She thinks I'm with TMZ." He and wife Molly McNearney have also set the bar pretty high for themselves as parents. "Rest assured we're going to do everything in our power to make this the best baby since a cute little guy named Jesus," he said.
