The new NBC comedy from creator Jimmy Fallon stars three thirtysomething guys — Jesse Bradford, Zach Cregger and Anthony Anderson — enjoying the adventures of parenting even though they haven't grown up fully themselves. Hayes, who also starred on CBS' short-lived Worst Week, will play Shelia, the controlling Type-A ex-wife of Chris (Bradford) with whom he shares custody of their 9-month-old son.

Hayes replaces Sara Rue, who played the role in the pilot. Rue will instead star on ABC's new comedy Malibu Country.

Guys with Kids premieres on Sept 26 at 8:30/7:30c.
