Will Arnett and Amy Poehler put their kids first.

The former couple - who have two sons, Archie, four, and Abel, two, together - split last September after nine years of marriage but still help each other balance parenting and work.

'Arrested Development' star Will told People magazine: ''We figure it out. Everything else is second fiddle to your kids. Work doesn't even come close. It's the best thing in the world to watch them grow.

''Fatherhood has completely altered my life for the better. It puts everything in perspective. I'm overall a much happier person that I was [before I was a father].''

It was recently claimed Amy has moved on from Will and started dating 'New Girl' actor and comedian Nick Kroll.

The duo were spotted looking ''cosy'' on a date at Pikey Café and Bar in New York in March.

An eyewitness said: ''No one really recognised them.''

Sources revealed that it wasn't the couple's first date but spokespersons refused to comment on their relationship.

Nick, 34, has known Amy, 41, for some time as he previously appeared on two episodes of her series 'Parks and Recreation' in 2011. He also filmed an episode this year.
