'The Office': Jenna Fischer says another Halpert baby is coming

Jenna Fischer is pregnant in real life, and the producers of "The Office" have decided to roll with that fact.

So Cece Halpert, get ready to meet your little brother or sister.

"Pam will be pregnant when the season starts," Fischer tells Vulture. "Pam and Jim [John Krasinski] snuck away last season on Valentine's Day, and they had sex. The story is that they conceived this baby at that time and were keeping it a secret until we come back from the summer."

Fischer and her husband, Lee Kirk, announced in May that they're expecting their first child -- and coincidentally, they conceived their baby around the time that "The Office" was shooting its Valentine's day episode, titled "PDA," early this year.

"The Office" begins shooting its eighth season later this month and will premiere Thursday, Sept. 22 on NBC.
