Amy Poehler and Will Arnett

Amy Poehler and Will Arnett

"Saturday Night Live" continued as planned ... even though Amy Poehler was missing from the Weekend Update desk for a very good reason.

The actress was in labor all day Saturday (Oct. 25) in New York to give birth to her son, the first child for Poehler and her husband, Will Arnett.

"I can confirm that Amy gave birth to Archie Arnett on Saturday," says Lewis Kay, Poehler's spokesman, in a statement.

Little Archie weighed 8 lbs., 1 oz. at birth. He and his mom are "healthy and resting comfortably."

On the NBC live sketch comedy show, fellow cast mate Seth Meyers sat at the Weekend Update desk and announced, "I'm Seth Meyers. Amy Poehler is not here because she is having a baby."

The Update segment ended with "SNL" alum Maya Rudolph -- who had returned to play Michelle Obama, wife to Sen. Barack Obama -- singing "Can't Take My Eyes off of You" with Keenan Thompson, replacing the lyrics "Oh pretty baby" with "We love you, Amy" in tribute to the new mom.

Poehler manned the anchor desk last Saturday (Oct. 18) and performed a rather memorable Alaska rap. She had sucess earlier in the year in the big-screen "Baby Mama" with former "SNL" cast mate Tina Fey. Poehler has said that she won't return to "SNL" once her maternity leave is done.

Arnett, 38, is best known for playing George Oscar "G.O.B." Bluth II on "Arrested Development," on which Poehler played his nameless wife. The two also collaborated in "Blades of Glory," playing the amorous brother-sister ice skating team. His recent credits include "Semi-Pro" and " Horton Hears a Who."
