Heath Ledger feared cocaine would kill him, according to a nightclub owner who alleges he took the drug with the late star. John-Bruce Shoemaker has come forward with his claims just one week after Ledger was found dead in his New York apartment at the age of 28.

Shoemaker claims he supplied Ledger with cocaine at his Prague nightclub Marquis De Sade when the Australian star was in the Czech capital to shoot movies A Knight's Tale and The Brothers Grimm in 2000 and 2003.

He tells the National Enquirer, "I supplied him with cocaine and we did it together. There were lots of beautiful girls in my club, but he was only interested in drugs."

And Shoemaker claims Ledger once told him, "If I'm not careful, this stuff would kill me."

An autopsy was unable to establish the cause of Ledger's death, although police believe his death could be drug-related as five different bottles of prescription drugs were found around his apartment.
