An impostor pretending to be Heath Ledger's father fooled Tom Cruise into consoling him over the phone — and nearly got John Travolta to buy him a plane ticket to the United States, sources told the New York Post.

The con artist also tricked the Frank E. Campbell Funeral Home in Manhattan, where Ledger's body was held before being flown to Los Angeles, into booking him and his "family" rooms at the Carlyle hotel nearby on Madison Avenue, sources told the Post.

The man falsely claiming to be Kim Ledger also spoke on the phone with the doctor who performed the autopsy on the "Brokeback Mountain" star, a spokeswoman for the Medical Examiner's Office confirmed for the Post.

Cops want to arrest the scammer on fraud and larceny charges, and sent detectives to Ledger's wake at the funeral home Friday in hopes of catching him, New York City Police Commissioner Ray Kelly told the Post.

But police do not know the identity of the impostor, who "had a couple of conversations with" Tom Cruise asking for emotional support, a source told the Post. Cruise abruptly cut him off when he learned "he was an impostor," the source said.

Ledger, 28, was found dead last Tuesday. A cause of death has not yet been determined.
