Live from New York...it's a Saturday night baby.
"Mother, baby and husband are all healthy and resting comfortably," NBC said in a statement.
The birth announcement came courtesy of Poehler's "Weekend Update" tag-team partner, Seth Meyers, at the opening of the fake news segment:
"Amy Poehler is not here tonight because she's having a baby. Now here are tonight's other top stories..."
Poeher previously confirmed that she would not return to SNL as a regular after maternity leave, though she and producers were hoping Archie's grand debut would hold out until after the election.
After a stint on diaper duty, Poehler will begin work on a new NBC sitcom from the brain trust behind The Office.
