Will Arnett has reportedly filed for divorce from Amy Poehler.
The 43-year-old actor, who currently stars on "The Millers," filed for divorce in Los Angeles Superior Court on April 8, People magazine reports. He is seeking joint legal and physical custody of the couple's two sons, Archie, 5, and Abel, 3, as well as visitation rights.
The filing comes 18 months after the couple announced their separation in September 2012. Arnett, 43, and Poehler, 42, wed in August 2003 and have appeared together in several films including "Blades of Glory" and "Spring Breakdown."
Poehler also made several appearances on "Arrested Development," in which Arnett stars as George "Gob" Bluth II, and Arnett appeared on a 2010 episode of Poehler's series "Parks and Recreation."
This was Poehler's first marriage and Arnett's second. He was previously married to actress Penelope Ann Miller for a year before they divorced in 1995.
