Comedians Amy Poehler, 40, of Saturday Night Live and Parks and Recreation, and Will Arnett, 42, of Arrested Development and Up All Night, are calling it quits after nine years of marriage and two children together, sons Archie, 3, and Abel, 2.

Poehler and Arnett have been known not only for their highly acclaimed individual comedic accomplishments, but also for their onscreen roles together, dating back to Blades of Glory and Spring Breakdown, as well as voice work in Horton Hears a Who! and Monsters vs. Aliens.

Each has also made guest appearances — ironically as ill-fitting romantic choices for each other — on the other's shows. Pohler played Gob Bluth's unnamed one-night-stand-turned-bride in several episodes of Arrested Development, and Arnett portrayed Leslie Knope's blind date gone wrong in Parks and Recreation.

The split is reportedly "very amicable," a source told Us Weekly. A rep for Arnett and Poehler confirmed the separation.

Both Poehler and Arnett are up for Primetime Emmy Awards on Sunday, September 23, 2012. Poehler is nominated for Outstanding Lead Actress in a Comedy Series and Outstanding Writing for a Comedy Serires, while Arnett is going for Outstanding Guest Actor in a Comedy Series for his work as Jack Donaghy's (Alec Baldwin) nemesis, Devon Banks, in NBC's 30 Rock.

Prior to Poehler, Arnett was briefly married to Penelope Ann Miller, 48, for one year in 1994-1995.
