Tina Fey is opening up about former co-star Tracy Morgan's life-threatening car crash, and the 30 Rock star said she was shocked Morgan lived through the horrific accident.
"I honestly can't believe that he made it," Fey said in an interview with Howard Stern on Monday. "He was so frail before [the accident], he was so diabetic. And now, for him to have survived that, it's incredible."
