The 30 Rock baby boom continues – Jane Krakowski is a mom.
The actress, 42, gave birth to son Bennett Robert Godley on Wednesday, April 13 in New York City, her rep confirms to PEOPLE.
The baby boy – who has blond hair like Mom – weighed in at 7 lbs., 12 oz., and is the first child for Krakowski and fiancé Robert Godley.
“Bennett is an amazing, healthy sweet boy and we are both just crazy in love with him,” Krakowski says.
Thursday night on the special, one-hour 100th episode of 30 Rock, Krakowski’s character, Jenna Maroney, toyed with the idea of having a baby – for the publicity it would bring her. It was the first time Krakowski’s baby bump was shown on the program.
