Back in December, we informed Matt Damon that he was at the top of Tina Fey's 30 Rock guest star wish list. His response? "I would do [30 Rock] in a heartbeat if they asked me to come on," enthused the genuinely shocked thesp. "She should call my people -- or even better me. Or I could call her. Let's make this happen."
Cut to March 31 and voila: Sources confirm to me exclusively that Matt Damon is going to guest star on 30 Rock!
