Jimmy Fallon is one proud papa, dedicating his opening monologue last night to his newborn daughter.

The "Late Night with Jimmy Fallon" host opened up the show by declaring "I'm your host, Dada!"

Jimmy and wife Nancy Juvonen Fallon welcomed a baby girl on Tuesday at 6:21 a.m.

"I'm the father of a beautiful baby girl, she's so cute," Fallon said on his show last night -- still wearing the hospital band around his wrist as he talked. "Her name is Winnie Rose Fallon and she's so cute. She's 5 pounds, 9 ounces. She's so cute...me and my wife are so happy and thank you all for the well-wishes."

It's adorable seeing how happy the 38-year-old is about his family's new addition -- and we love the jab at the other baby, Prince George Alexander Louis of Cambridge.

Winnie is the couple's first child. They've been married since 2007.
