'Late Night" host Jimmy Fallon can expect some late nights at home as a proud new papa, reports The Associated Press. A representative says Fallon and his wife, Nancy Juvonen Fallon, welcomed a baby daughter Tuesday morning. The publicist says the first-time parents are "overjoyed." He and his film-producer wife were wed in 2007. Fallon, 38, takes over NBC's "The Tonight Show" from Jay Leno next year after hosting "Late Night" since 2009.
