Jimmy Fallon Nancy Juvonen baby - Just over a year after announcing the birth of his first daughter, The Tonight Show host has welcomed another baby girl into his family.

An inside source confirmed the birth of the new Jimmy Fallon Nancy Juvonen baby girl, who has reportedly been named Frances.

"Frances Cole Fallon officially entered the world at 8:45 a.m. on Dec. 3, weighing 5 lbs., 11 oz. and is 18.5 inches long," a statement from the source reads.

The latest Jimmy Fallon Nancy Juvoven baby, Frances, as well as her elder sister Winnie, who is just 16 months old, were reportedly born by a surrogate mother. Fallon and his wife reportedly chose to keep their new baby girl a secret until she was born.

The comedian, who is also a children's book author, had made jokes about the strenuous experience of caring for his first child. Doubtless, he will have much to say about his experience with Frances. NBC tells E! News that Fallon has been forced to cancel the taping of The Tonight Show for two nights in order to spend some time with the newest member of his family.

The news of the birth of Jimmy Fallon and Nancy Juvonen's baby has made headlines. Many fans have sent congratulatory messages to the 40 years old comedian, and his wife, 47, who tied the knot about 7 years ago.

Meanwhile, judging from the tight-lipped circumstances surrounding her birth, fans will have to wait patiently for some time before any photos of the latest Jimmy Fallon Nancy Juvonen baby will be made public.

The first Jimmy Fallon Nancy Juvonen baby, Winnie, was born shortly before the comedian took charge of The Today Show from Jay Leno. The former Saturday Night Live funnyman has since cemented his place on late night television and has even won an Emmy award while at it.
