For first-time dad Jimmy Fallon, his little button Winnie is the best thing that’s ever happened to him.
“This has been the craziest year of my life,” the Tonight Show host recently told PEOPLE. “But being a father is the most exciting, amazing thing that ever happened to me. And everything’s going well on the show. My life has never been this cool.”
Fallon, 39, and his wife Nancy, 47, welcomed their daughter via surrogate on July 23, 2013.
Several other famous first-time dads have also been gushing over their little ones.
“What I’m learning — and what’s interesting — is that my wife has changed completely, and I’m sure that I have too,” Jason Biggs said at the PaleyFest earlier this spring.
Biggs’ wife Jenny Mollen gave birth to the couple’s first child — a son named Sid — on Feb. 15.
For Prince William, his son George reminds him of a certain prince (or princes).
“He’s a little bit of a rascal, I’ll put it that way,” the Duke of Cambridge told CNN last summer, weeks after the birth of Prince George.
“He either reminds me of my brother or me when I was younger, I’m not sure, but he’s doing very well at the moment . . . he’s growing quite quickly, actually. But he’s a little fighter — he wriggles around quite a lot and he doesn’t want to go to sleep that much.”
