Jeff Conaway, 60, who is best known for his role in the hit movie Grease and television show Taxi, is currently in critical condition following an apparent overdose.
The actor has had a very public problem with addictions to cocaine, painkillers and alcohol, even being seen in 2008 on the VH1 reality series Celebrity Rehab. According to his family members, he is currently unconscious with pneumonia at Encino Hospital Medical Center.
In January 2010, Conaway fell down a staircase and suffered a broken hip, a broken arm, a fractured neck and a brain hemorrhage.
