William & Kate aren't the only ones welcoming their first child this week.

Late Night host Jimmy Fallon and wife Nancy Juvonen Fallon welcomed their first child, a baby girl, on Tuesday.

A rep for Fallon told PEOPLE the couple are “overjoyed about the arrival of their beautiful daughter.” Fallon, who will take over The Tonight Show from Jay Leno next year, married Drew Barrymore’s Flower Films producing partner in December 2007. This is their first child.
