French rock star Johnny Hallyday has emerged from a medically induced coma after undergoing surgery in a Los Angeles hospital, BBC reported.
Hallyday, 66, was admitted to Cedars Sinai hospital to be treated for an infection allegedly received during an operation for a slipped disc in Paris.
Doctors put him in a coma on Friday in order to conduct two operations.
Hallyday, who has been active since the 1960s, has a passionate following in the French-speaking world.
He has had a series of health problems since treatment for cancer of the colon earlier this year, and was operated on in Paris for a back injury suffered during his latest farewell tour.
Controversy flared up over the operation, performed by surgeon Stephane Delajoux, who was beaten up on a Parisian street on Saturday.
The surgeon's lawyers insist there was "absolutely no negligence" during the operation.
