Here's a shocking twist in rock 'n roll history. Marianne Faithfull claimed in a recent interview with Mojo magazine that Doors frontman Jim Morrison's 1971 Parisian bathtub death was, actually, a murder—and it involved her ex-boyfriend Jean de Breteuil.

The singer/songwriter, 67, recalled that fateful summer when she traveled to France with de Breteuil, a heroin dealer whose clients included several high-profile celebs. Upon their arrival, Faithfull's beau told her he had to stop by the Lizard King's apartment, located at 17 Rue Beautreillis.

"I could intuitively feel trouble," Faithfull recalled, resulting in her taking "a few Tuinal" and conking out. "He went to see Jim Morrison and killed him," she claimed. "I mean I'm sure it was an accident. Poor bastard."

"The smack was too strong?" she speculated to herself. "Yeah. And he died. And I didn't know anything about this. Anyway, everybody connected to the death of this poor guy is dead now. Except me."

While Morrison is long gone, the numerous conspiracy theories regarding his death continue to thrive. At the time, French authorities decided to skip the autopsy as no foul play was believed to be suspected in his death.

As for Jean de Breiteuil? The former dealer died of an overdose in Morocco that same year. "He was a horrible guy, someone who had crawled out from under a stone," Faithfull recalled in her 2000 autobiography. "What I liked about him was that he had one yellow eye and one green eye. And he had a lot of dope. It was all about drugs and sex."

In the same interview with Mojo, Faithfull also discussed another fallen music legend, Amy Winehouse, who, like Morrison, also died at age 27. "Amy was very, very wary of me," Faithfull said. "She knew that I knew and she didn't want me to say anything. There's a level of narcissism which is all mixed up with self-hatred. I know it well…. But I can't think what I could have done apart from take her and shake her! 'You stupid little c—! Wake up!'"

Faithfull is back in the news as her new album, Give My Love to London, is released on Sept. 29.
