Surprise! Jimmy Fallon shocked the world when he and his wife Nancy Fallon (nee Juvonen) welcomed a baby girl via surrogate on July 23. "My wife and I had been trying a while to have a baby. We tried a bunch of things -- so we had a surrogate," Fallon explained to Savannah Guthrie in a Today show interview. "We said, 'We're not going to tell anybody.' It'd be just more fun if it's just private between me and my wife. And then we get to introduce her to everybody."
