Poehler is a " Saturday Night Live" alum who currently stars in the NBC show, "Parks and Recreation."

Sources tell Zap2it that Amy's pregnancy is the reason the sophomore series got picked-up earlier than the other NBC comedies, enabling them to film the beginning of the fall season before they break for hiatus.
