Jeff Conaway in a coma after overdose: 'Grease' actor found unconscious

jeff-conaway-getty.jpgOn the heels of the news of Zsa Zsa Gabor having fallen into a coma, we've got another sad story. Jeff Conaway, best known as Kenickie in musical phenom "Grease," has also slipped into a coma following a possible overdose.

Initial reports said that the actor was hospitalized during a bout of pneumonia, but a rep confirms that his condition is more serious than that. "He is unresponsive at this time. He turned his head two days ago, but nothing since," the manager tells E!, remaining mum regarding on what drug Conaway overdosed.

Conaway, 60, was found unconscious on May 11 and is currently in critical condition at an Encino hospital.

Though Conaway shot to fame in 1978 as Kenickie, his career floundered in the '80s and '90s, largely due to his substance abuse problem. He was recently on the pop culture radar for his consecutive stints on "Celebrity Rehab with Dr. Drew." Unfortunately, Conaway was unsuccessful in staying sober.
