There's been an outpouring of love and concern on Twitter for comedian Tracy Morgan
, who was critically injured in a fatal bus crash
The former 30 Rock
star, 45, was traveling back from a show in Delaware on Saturday morning when the limousine bus he was riding in was involved in a multi-vehicle accident on the New Jersey Turnpike.
Morgan's friend, comedian James "Jimmy Mack" McNair, was killed in the accident, and two others, comedians Harris Stanton and Ardie Fuqua, were injured.
Morgan, a father of four, remains in intensive care in a New Jersey hospital.
"He's not in good shape," Morgan's ex-wife Sabina Morgan told the New York Daily News
. "I'm traumatized. I'm so upset. I can't believe it. It's like I'm in a nightmare."
