Katie Louise Gaffigan is a younger daughter of Jim and Jeannie Gaffigan. She got her second name in honor of her maternal grandmother.
Katie, whom Jim nicknames Koo koo, isn’t afraid of being in the spotlight. She starred in a 2017 Chrysler Pacifica TV commercial as well as visited a Frozen premiere in 2014 with her big family. Despite her young age, Katie already has her personal Instagram account and frequently appears on her parents’ ones.
A curious fact: though Jim often takes Katie and her siblings on the tours, he reveals that he doesn’t like traveling with them.
