One of the celeb couples that everyone seems to actually like is no more: Amy Poehler and Will Arnett are separating after a nine-year marriage, reports US Weekly. At least "it's very amicable," according to the magazine's source. Their publicist confirmed the news to AP. SNL alum and Parks and Recreation star Poehler is 40, while Arnett, star of Arrested Development and the current Up All Night, is 42. They have two sons, Archie and Abel, ages 3 and 2.
