French rocker Johnny Hallyday fell into a coma at the end of last year (09) as a result of his alcohol intake, according to a new report.
The 66 year old is currently taking legal action against his surgeon to determine whether he botched a back operation which left the star in the artificial coma in December (09).
Hallyday left a Los Angeles medical centre following corrective surgery on his back to repair damage allegedly caused by a procedure to correct a herniated disc in Paris in November (09).
Following the operation the singer claimed he "came very close to death".
An infection specialist and neurosurgeon is now studying Hallyday's medical records before making a decision in the case against Stephane Delajoux, who performed the initial operation.
But documents allegedly leaked from L.A.'s Cedars-Sinai Medical Center suggest the singer was put into a coma by doctors after drinking "incredible" amounts of booze, reports L'Express magazine.
The French publication alleges the procedure was to alleviate the effects of alcohol on his system, with the records reportedly detailing "excessive alcohol consumption".
The infection specialist and neurosurgeon have until 15 July (10) to produce their report into the incident.
