Jane Krakowski (Ally McBeal) will join the cast of NBC's new comedy 30 Rock, playing the star of "The Girlie Show," a network variety show that serves as the backdrop for the workplace comedy.

The new series debuts on October 11 and will air on Wednesdays from 8:30 p.m. to 9:00 p.m. ET/PT on NBC.

"Jane is enormously talented and everyone is thrilled that she is joining the cast. I think it's going to be a perfect fit," said executive producer Lorne Michaels.

30 Rock is told through the comedic voice of Fey and features Alec Baldwin ("Jack Donaghy") as the brash new network executive who has turned the show upside down with his meddling ways. Single Lemon is living every comedy writer's dream - head writer on a demanding, live TV program in New York City. Her life is jolted when Donaghy (Baldwin, The Aviator, The Cooler)interferes with her show, and bullies Lemon into convincing Tracy Jordan (Tracy Morgan, NBC's Saturday Night Live, The Longest Yard), a wild and unpredictable movie star, to join the cast. Now Lemon must manage the unmanageable so that the show - and her dream - can go on.

Also rounding out the cast in the half-hour comedy are Scott Adsit ("Pete Hornberger")as the variety show's producer and Jack McBrayer ("Kenneth the Page")as the over-eager NBC 'Page' - a highly sought after entry level position with the network. Rachel Dratch (Saturday Night Live) will appear in multiple episodes, playing a variety of different characters on the series.
