Amy Poehler, Nick Kroll Amy Poehler, Nick Kroll

Amy Poehler and Nick Kroll are splitting up after two years of dating, Us Weekly reports.

A source close to the couple tells Us their conflicting schedules were to blame. "They really tried, but it just wasn't realistic anymore," the source says. "They were spending more time apart than together."

Kroll, who was the first person Poehler dated after divorcing actor Will Arnett, did not accompany Poehler to the Emmy Awards on Sunday.

Poehler and Arnett were married for nine years until they divorced in 2012. They have two sons together, ages 6 and 5. Poehler discussed her relationship with Krohl in her memoir Yes Please, which was released last year.
