Nearly two years after the couple separated, Will Arnett has filed for divorce from Amy Poehler. The Arrested Development star is requesting joint legal and physical custody of his two young sons with the Parks and Recreation funny gal, and also wants visitation rights. Since their amicable 2012 split, Will was briefly linked to celeb chef Katie Lee and then to producer Erin David, while Amy has been in a relationship with comedian Nick Kroll since May 2013.
