One of Jack Donaghy's ex-girlfriends is coming to 30 Rock - and it's a very familiar, serious face.

Former Secretary of State Condoleezza Rice will guest star on the NBC sitcom next month, portraying herself and following up on a fictional relationship that Jack teased on season one.

Tina Fey announced the news during a book signing this week, telling The Washington Post that the episode will focus on Jack growing upset when sees Rice with Vladimir Putin.

What kind of memorable 30 Rock quotes will Rice deliver? TV Fanatic will be there to record each and every one.
