Jimmy Fallon and wife Nancy Juvonen welcomed their second baby girl into the world on Wednesday (December 3). Frances Cole Fallon was born at 8:45 a.m., weighing in at 5 pounds, 11 ounces and measuring 18.5 inches long.

Frances Cole joins big sister Winnie Rose, who was born just 16 months ago in July 2013. Both daughters were born via surrogate.

If Fallon's "The Evolution of Dad Dancing" skit from this past Father's Day is any indicator of how the "Tonight Show" host is growing into fatherhood, these two little girls have a lifetime of embarrassing laughs ahead of them.

While the comedian perfects his Belt Grabber and Lawn Mower moves, he'll also be ensuring that Frances' first word is "Dada." Winnie's first word was "Mama," which prompted Fallon to publish his second children's book, "Your Baby's First Word Will Be Dada."
