Startling new revelations in mystery death of THE DOORS legend JIM MORRISON as 1960s chanteuse MARIANNE FAITHFULL claims her heroin dealer administered the death dealing drug.

For those of you who hace come in late, Jim Morrison, the Lizard King,  died in a Paris bathtub in 1971 of an alleged heroin overdose.

While bizarre theories have swirled around his death, now, Mick Jagger’s former flame, singer Marianne Faithfull, says one of her ex-boyfriends, heroin dealer Jean de Breteuil, administered the fatal drug.

He “went to see Jim Morrison and he killed him. The smack was too strong? Yeah. And he died,” Faithfull told Mojo magazine.

 “I’m sure it was an accident.”

According to the “As Tears Go By” singer, she could “intuitively feel trouble” when de Breteuil (a French count known as “the heroin dealer to the stars”) went to see Morrison.

Based on her hunch, she didn’t go with him.

“I thought, I’ll take a few Tuinal (barbiturates) and I won’t be there,” said Faithfull.

Morrison died on July 3, 1971 at age 27 with his girlfriend Pamela Courson finding the body in their Paris apartment’s bathtub.

In 1974, Courson died of a heroin overdose, also at 27.

Faithfull noted of “The Light My Fire” powerhouse Morrison, “Everybody connected to the death of this poor guy is dead now.

“Except me.”
