Comedians Amy Poehler and Will Arnett have welcomed their first child, a boy.

Archie Arnett was born on Saturday and weighed in at 8 lbs., 1 oz., their rep Lewis Kay said in a statement.

"Amy, Will and Archie are all healthy and resting comfortably," Kay said.

During the "Weekend Update" segment of Saturday Night Live, Poehler's co-anchor Seth Meyers announced to a cheering crowd: "Amy Poehler is not here tonight because she is having a baby."

Besides welcoming the new member of the family, Arnett will star with Kristen Bell in the big-screen comedy When in Rome, and Poehler - who is leaving SNL this year - will return to NBC in the spring as the star of an as-yet-untitled primetime comedy.
