Jimmy Fallon and his wife, Nancy Juvonen, welcomed their second child on Wednesday. People confirms that the Tonight Show host and his wife are now parents to a baby girl; a rep for the couple said, "Frances Cole Fallon officially entered the world at 8:45 a.m. on December 3, weighing 5 lbs., 11 ounces and is 18.5 inches long," adding, "Their new addition joins big sister, Winnie Rose, 1. The couple opted to keep their baby joy to themselves until their new daughter, Frances Cole, made her official debut. Both Fallon babies were born via surrogate." Jimmy and Nancy became first-time parents in July 2013 when their daughter Winnie was born. The late night host gushed about fatherhood back in June, telling People, "Being a father is the most exciting, amazing thing that ever happened to me. . . . I never knew I could be this happy, and that's the truth." Congrats to Jimmy and Nancy on their new arrival!
