Pictures of Tina Fey, Alec Baldwin, Pregnant Jane Krakowski, and Tracey Morgan Celebrating 100 30 Rock Episodes 2011-03-11 02:02:00

Tina Fey and Alec Baldwin had the honor of cutting a big cake in the shape of 30 Rockefeller Plaza last night as they celebrated the 100th episode of 30 Rock. The duo was joined by Tracy Morgan and Jane Krakowski, who says her pregnancy has made her trendier than ever, and other stars of the show. The celebration wasn't held in the iconic Manhattan building, but across the river at Queens's Silvercup Studios where much of the series is shot. TIna and her cast were the ones celebrating the momentous occasion, but it turns out fans are getting a present too with a special one-hour episode on April 21! It's been a busy few days for Tina in particular, as she balances filming with her philanthropy and writing careers. We weren't treated to a new installment last night, but hopefully they'll be back to owning the Thursday NBC lineup next week.
