Forget the 30 Rock quotes she pens every week.

Tina Fey delivered two words during an interview with Oprah this week that will be far more memorable than anything Jack Donaghy has ever uttered: I'm pregnant.

During a chat that will air on April 12, the actress admitted she's five months along with her and husband Jeff Richmond's second child. Their first, a girl named Alice, is five years old.

Fey appeared on the program to promote her new memoir, Bossypants, which went on sale this week. We're so happy for the funniest woman on television!
