Saturday Night Live star Amy Poehler and Arrested Development‘s Will Arnett have welcomed their first child, a baby boy. Son Archibald ‘Archie’ William Emerson Arnett was born on Saturday, October 25th in New York City, weighing in at 8 lbs. 1 oz. Amy, Will, and Archie are all healthy and resting comfortably, Amy’s rep shares. Archie is named after dad, whose full name is William Emerson Arnett.

After rumors began last spring, Amy, 37, and Will, 38, announced the pregnancy in April, explaining that they wanted a delivery surprise. Amy stayed busy during her pregnancy — being nominated for an Emmy, speaking at a Presidential Politics panel discussion, and trying to keep her bump covered on SNL! Will, for his part, contributed baby names.
