Amy Poehler and Will Arnett are expanding their brood!

A rep for the Parks and Recreation comedienne confirms exclusively to that the couple is expecting their second child. No due date has been released.

The baby will join big brother Archie, 16 months.

Poehler, 38, married Arnett, 39, in August 2003.

 "Any working mother will tell you it's a day-to-day thing," Poehler told TV Guide last November of juggling work and motherhood. "You just do your best and try to make it work."

The comic star added that she and fellow Saturday Night Live alum Tina Fey trade stories about being Hollywood moms. "We [talk] a lot about how we're both working long hours with kids. Our emails and texts are mostly about formula and nannies."
