Congratulations to funnyman Jimmy Fallon and his wife Nancy Juvonen who today (July 23) became first time parents!

The couple welcomed a baby girl into the world this morning, their rep told People, adding that the two are "overjoyed about the arrival of their beautiful daughter." No name has been announced as of yet.

If you find yourself thinking you've been out of the loop for too long, fret not -- no one had any idea the two were expecting! And to think just yesterday Fallon was cracking jokes about the arrival of the royal heir:

Fallon, 38, and Juvonen, 46, got married in 2007 after meeting on the set of the movie "Fever Pitch" -- in which the late night host starred alongside Drew Barrymore, who's Juvonen's producing partner.

Tonight the SNL alumnus was supposed to have Louis CK on his show as well as Shailene Woodley. Instead, NBC aired a rerun.

Next year, Fallon is set to take over "The Tonight Show" from Jay Leno.
