Jeff Conaway, who starred in the series 'Taxi' and the film 'Grease,' has battled addictions to cocaine, alcohol and prescription painkillers since he was a teenager and talked about his struggles on the VH1 reality series 'Celebrity Rehab with Dr. Drew' in 2008.

Conaway died on May 27, 2011 at age 60 after battling pneumonia and sepsis in a hospital. CNN had quoted a source close to the actor as saying that Conaway's 'use of drugs caused him not to realize how ill he was, keeping him from getting treatment until it was almost too late.'
