Will Arnett attended estranged wife Amy Poehler's 41st birthday party over the weekend.

The Blades of Glory couple recently announced they were separating after nine years of marriage, but insisted the split was amicable and Will proved that by turning up at the bash on Sunday. The actor arrived with the couple's two sons, Archie, three, and two-year-old Abel, at the party in Hollywood and insiders say things were very civil between the former couple.

Despite their decision to part ways, an insider close to the pair say the comedians "have a lot of respect for each other" and "there's still love between them." Speaking about their relationship in 2007, Amy said, "People think we sit around and make each other laugh and stuff. But we're real homebodies."

Will has previously said he "immediately had a talent crush" on Amy when he met her, adding, "The first time I saw her onstage, I said, 'I'm gonna marry that girl."

The marriage was Amy's first, and Will's second after he was wed to actress Penelope Ann Miller for one year until 1995.
