Crouching in a dark corner, Lindsay Lohan is poised to inject herself with what appears to be a syringe of heroin.
The shocking picture shows the troubled Mean Girls star wrapping a tourniquet around her lower arm - the method addicts use to raise a vein.
Her right hand hovers the needle over the skin of her left arm.
The horrifying revelations will compound fears about the extent of LiLo's breakdown -- as she was returned to jail this week for a third time. Lohan, 24, was released Friday following her 15 hours behind bars after posting $300,000 bail.
This was a result of her failing a court-ordered drugs test for cocaine, which was in breach of her probation stemming from a 2007 conviction for drink-driving and cocaine possession.
This is the first time there has been evidence that Lohan may have been dabbling in harder drugs like heroin, which is commonly injected.
