Poehler's pregnancy affects 'Parks' production

Expecting second child with husband Will Arnett

Amy Poehler and Will Arnett are expecting a second child.

Poehler's pregnancy is not going to be written into her NBC series "Parks and Recreation," which has been renewed for a third season.

The pregnancy is expected to affect the show's production schedule for next season as she will deliver in the summer or early fall.

To minimize the effect, "Parks" will stay in continuous production after it wraps season 2 to bank episodes for next season.

Poehler had the couple's first child in Oct. 2008 while on "Saturday Night Live." She famously rapped alongside Sarah Palin just days before giving birth.
