So, we guess this makes it really official (sad face)?
E! News has confirmed that nearly a year and a half after announcing their split, Will Arnett has filed for divorce from Amy Poehler.
Arnett filed the papers in Los Angeles Superior Court last week, and is asking the court to award Poehler and him joint physical and legal custody of their two sons Archibald and Abel, according to documents obtained by E! News.
The pair revealed that they were separating in September 2012 after nine years of marriage.
The "Parks and Recreation" star and the "Arrested Development" alum have collaborated on several projects together, including "Blades of Glory," "Monsters vs. Aliens" and "Horton Hears a Who!" In 2010, Arnett made a guest appearance on Poehler's hit NBC comedy.
This was Arnett's second marriage--he was divorced from Penelope Ann Miller after one year of marriage in 1995--and Poehler's first.
"All people have been doing since the dawn of time is trying to figure out how to live this life and be happy," Arnett said of their divorce. "I'm no different. I'm 43, and I've found my happiness--which is my kids."
