SAD... cocaine, prescription drugs, and alcohol have taken its toll.
Jeff Conaway will be taken off life support machines after doctors told the 'Grease' actor's family that he has had no brain activity since being admitted to a hospital May 11. "The feeding tube has already been removed. The ventilator which is breathing for Jeff, will be removed sometime this afternoon," a source close to the situation told RadarOnline.com.
The former Taxi star was hospitalized on May 11 for what was though to be a prescription drug overdose.
Dr. Drew Pinsky, who treated Conaway on "Celebrity Rehab," later said the star of Grease, 60, was suffering from pneumonia and sepsis, a severe illness in which the bloodstream is overwhelmed by bacteria, and had slipped into a coma.
The source said no measures will be made to revive the actor, saying, "Jeff is in no pain whatsoever."
