Jeff Conaway, alum of Celebrity Rehab and star from Grease and Taxi, has officially slipped into a coma. The actor is in critical condition after overdosing last week. The 60-year-old was found unconscious after possibly overdosing on pain pills.
The star's manager told E! Online, "He is in a coma and unresponsive at this time. He turned his head two days ago, but nothing since."
Pretty scary since doctors haven't confirmed whether or not they think he will come out of the coma. Jeff is currently in a hospital in Encino, Calif. Back in 2008, he joined Celebrity Rehab and shared the dark secrets about his addictions to alcohol, painkillers and cocaine.
