After nine years of marriage, AMY POEHLER and WILL ARNETT have separated.  A source says, "It's very amicable."  They have two sons together, ages 2 and 3.

Amy is, of course, the star of "Parks and Recreation", and "Saturday Night Live" before that.  Will is currently filming a new season of "Arrested Development" for Netflix.  They've worked together on "Blades of Glory", "Horton Hears a Who!" and "Monsters vs. Aliens".

This was Amy's first marriage, and Will's second.  He and PENELOPE ANN MILLER divorced after a year of marriage back in 1995.
