Ellie Kemper's Baby Only Calms Down When He Sees Allison Williams

Ellie Kemper’s baby is keeping his parents busy.

Appearing on “Late Night with Seth Meyers,” the actress talked about her adventures as a new mom. Kemper and her husband, Michael Koman, have a 10-month-old son named James.

“James is a ... spirited child,” she told Meyers. On a flight to Los Angeles a couple of months ago, Kemper and Koman struggled to calm their fussy baby, but nothing worked ... until they showed him the airline magazine with Allison Williams on the cover. 

“Her gorgeous face delighted my child,” the mom said. “It was the only thing that worked.”

Since then, Kemper has used different magazines that feature Williams to make James smile.
