After being hospitalized on May 11th for what was thought to be a drug overdose, Grease star and former Celebrity Rehab patient Jeff Conaway is to be taken of the life support that has been sustaining him.

Family has been told that there is no brain function, and have already removed his feeding tube. A no resuscitate order has been issued.

The star’s family have been sitting vigil at the hospital since his admission, he was in a coma when he arrived. He has not woken since, and doctors have said that it is unlikely he will live without the breathing apparatus.

A source close to the situation spoke with RadarOnline saying “Doctors advised the family that Jeff has had no brain function since he was brought into the hospital.”

“The feeding tube has already been removed. The ventilator which is breathing for Jeff, will be removed sometime this afternoon. No measures will be made to try and revive him once the breathing tube is removed,” the friend added.

“Jeff has remained unconscious and is unaware of what is going on.”

According to Dr. Drew Pinsky who treated Conaway on Celebrity Rehab, the actor now 60 is suffering from pneumonia and sepsis and as a result slipped into a coma.

Our thoughts are with his family at this difficult time.
