After announcing the name of his baby girl on his show Late Night with Jimmy Fallon, Jimmy Fallon showed off his newborn, Winnie Rose Fallon, on Instagram.

He captioned the picture “I would like to introduce... Winnie Rose Fallon.”

The late night talk show host, 38, gushed about Winnie on his show on Wednesday. He also took the opportunity to joke, saying "I hope I don't screw this up” and “She's 5 pounds, 9 ounces. I got down to the ounce—that's how I weigh myself as well. I've gotta lose a couple of ounces."

Fallon’s rep told People he and his wife, Nancy Juvonen, who he’s been married to since 2007, are “overjoyed about the arrival of their beautiful daughter.”

The former Saturday Night Live cast member also said on Wednesday, “Thank you all for all the well-wishes on Facebook and Twitter and the blogs. I’m just so happy.”

Winnie Rose was born on Tuesday.
