Jimmy Fallon, 46, is often cracking jokes on his late-night talk show, but one thing that’s definitely no joke for Jimmy is his marriage to Nancy Juvonen, 54. The Tonight Show host and Nancy, a film producer, got married in 2007, and they will celebrate their 14th wedding anniversary this coming December. The couple has since expanded their family by welcoming two children: daughters Winnie Rose, 8, and Frances Cole, 6.
