Jimmy Fallon and his wife Nancy Juvonen surprised the world when they announced the birth of their second child earlier this month.

"The Tonight Show" host and his producer wife welcomed baby girl Frances Cole Fallon on Dec. 3 via surrogate. Little Franny joins big sister Winnie Rose, 1. This week, proud dad Jimmy introduced his newest daughter on his NBC show.

Fallon shared several photos on his cell phone of Franny on Monday night's episode of "The Tonight Show.

In one, the adorable infant is shown swaddled in a yellow and white blanket. The baby girl looks strikingly similar to her older sister Winnie.

In another pic, little Franny can be seen snoozing as she sits buckled up in her car seat.    

A third snapshot shows Franny nestled into what appears to be some sort of baby seat, her tiny face beyond precious.

Lastly, Jimmy shared a photo of him and wife Nancy beaming as they hold Winnie on the day the fourth member of the Fallon family arrived.

When Fallon became a father for the first time in 2013, he opened up about the miracle of welcoming a child on "The Today Show."

"I can't stop looking at her," Fallon told the "Today Show" anchors. "When I'm not holding her, I'm looking at photos of her on my phone. She's the coolest - the best thing to ever happen to me."

He also discussed his and wife Nancy's 5-year struggle to have a child.

"I know people have tried much longer (than we have), but if there's anyone out there who is trying and they're just losing hope ... just hang in there," said Fallon. "Try every avenue; try anything you can do, 'cause you'll get there. You'll end up with a family, and it's so worth it. It is the most 'worth it' thing."
