On September 24, actress Jenna Fischer, 37, and husband Lee Kirk welcomed a son, Weston Lee.

“Mom and baby are doing great,” her rep said.

Fischer’s pregnancy was written into her role as Pam on ‘The Office,’ and her fictional alter ego is expecting a little boy, as well.

Fischer and Lee, a screenwriter, have been married since 2010. It’s the first child for them both.
