Jimmy Fallon is one proud papa. He debuted his daughter, Winnie Rose Fallon, and oh my goodness is she precious.

The 'Late Night' host tweeted the above photo of his little girl by wife Nancy Juvonen Fallon:

Fallon and Juvonen Fallon welcomed Winnie to the world on July 23; Fallon announced the tyke's name on 'Late Night' on July 24.

"It's been a crazy couple of days -- well, actually, just one day," the affable 'SNL' alum said in his opening monologue (via Us Weekly). "It was just yesterday. It feels like I've had a four day conference."

He added, "It's very taxing on the fathers. I don't know how it is for the mothers, but [it's] very taxing [for us]. I'm emotionally drained."

He continued gushing, "I'm a father of a beautiful baby girl. She's so cute! Her name is Winnie Rose Fallon and she's so cute. She's 5 pounds, 9 ounces."

He clearly didn't lie. Congrats again!
