Devastating news: Last night at the National Dance Institute’s annual fund-raising gala, Alec Baldwin told Vulture that the next season of 30 Rock will be its last: “Our contracts are expired [in 2012], and Tina is gonna have a big career directing films and writing. She’s going to be the next Elaine May. She’ll be great.”
