HOLLYWOOD, Calif. — Amy Poehler and Will Arnett are expanding their comedy lines.

A rep for the Parks and Recreation star has confirmed to Us Weekly that Poehler is pregnant with the couple's second child.

Further information, including a due date, has not been released.

Poehler, 38, and Arnett, 39, welcomed their first child, 16-month-old son Archie, in Oct. 2008.

The Hollywood stars have been married since 2003.

"Any working mother will tell you it's a day-to-day thing," the former Saturday Night Live star said of juggling work and motherhood in an interview with TV Guide last November. "You just do your best and try to make it work."
