During a Today show interview recorded on Thursday night, Jimmy Fallon revealed that he and his wife Nancy Juvonen, 46, had their daughter Winnie, who was born on July 23, via surrogate.

"My wife and I had been trying a while to have a baby. We tried a bunch of things – so we had a surrogate."

The 38-year-old Late Night with Jimmy Fallon host also admitted in his interview with Savannah Guthrie that he had kept the pregnancy secret from both friends and colleagues.

"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." Which is exactly what the couple, who have been married since 2007, did.

We wondered why no one noticed that Nancy had been pregnant in the months prior to the surprising birth announcement -- it's because she wasn't! Secret or no secret -- we are happy for the new family of three!
