Troubled rocker Pete Doherty was reportedly revived by worried medics after he collapsed shortly before a gig.

The Babyshambles star was set to take to the stage at a porn theater in Graz, Austria on Thursday to perform before premiering his new autobiographical film. However the rocker allegedly went on a drug and alcohol binge before he was due to perform, according to Britain's The Sun newspaper.

Doherty was reportedly left unconscious after collapsing, and had to be revived by medics before taking to the stage four hours late. The star is said to have refused to be taken to the hospital for further treatment and managed to play a 45-minute set to fans.

Doherty's agent was unavailable for comment as WENN goes to press.
