Steven Tyler says that the chemotherapy he's undergone for almost a year "about killed me" but has also killed the hepatitis C infection with which he was diagnosed three years ago.

Tyler (fourth from the left in the Aerosmith promotional photo) revealed in an interview with Access Hollywood that he had the illness for a long time before exhibiting any symptoms of the chronic liver infection. After 11 months of chemo, the infection "is nonexistent in my bloodstream as we speak," Tyler said, "so it's one of those few miracles in doctoring where it's like a complete cure. It's gone."

Tyler was sidelined earlier this year for unrelated surgery to repair damaged vocal cords. Aerosmith is currently on tour with Mötley Crüe.
