Marilyn Monroe's state of mind before she died is set to be exposed by the US edition of Playboy.

The men's magazine will print the transcript of a taped free association monologue interview as part of a home session for her psychiatrist.

The transcript, which has never been seen uncensored before, begins, "I'm lying on my bed, wearing only a brassiere."

Monroe's thoughts will appear in the December 2005 issue.
