Jimmy Fallon cradled his newborn daughter, Winnie Rose, while leaving his home in NYC today. This is the first time we've seen the new dad out with his baby girl since she was born in July. Jimmy and his wife, Nancy Juvonen, welcomed their first child late last month. Jimmy announced the big family news in his Late Night monologue before sharing a sweet photo of Winnie on Instagram. The talk show host hasn't shied away from gushing about his little one her since her birth, saying: "I'm the father of a beautiful baby girl. She's 5 lbs., 9 oz. Me and my wife are so happy." We knew pretty early on that Jimmy would make an amazing dad, and this photo just proves it — he already looks like a total pro juggling his briefcase and baby!
