Legendary Hollywood heartthrobs Marlon Brando and James Dean may have been more than fellow celebrities.

LGBTQ Nation reports a new book,”James Dean: Tomorrow Never Comes,” claims Brando and Dean had a sexual relationship that went far beyond vanilla trysts.

Co-authors Danforth Prince and Darwin Porter interviewed Stanley Haggart who claims to have been a friend of Dean’s at the time. Haggart says Brando and Dean would engage in slave and slave master sex play with Brando as the slave master and Dean as the slave.

Haggart continued that Brando would force Dean to watch Brando have sex with strangers and make Dean wait outside Brando’s apartment in the cold begging to be invited for an S&M session.

“I got the impression that Jimmy was engaged in a cat-and-mouse affair with Brando, with Brando being the cat, of course,” Haggart says. “Brando seemed to be toying with Jimmy for his own amusement. I think Brando was sadistically using Jimmy, who followed him around like a lovesick puppy with his tongue wagging.”

The authenticity of the story can be debated considering Prince and Porter have famously written books making up sex stories for celebrities such as Steve McQueen and Peter O’Toole. However, Brando opened up in his own 1976 biography that he wasn’t afraid to admit he had same-sex experiences.

‘Like a large number of men, I, too, have had homosexual experiences and I am not ashamed. I have never paid much attention to what people think about me,” Brando wrote.

Rumors have swirled around Dean being bisexual or gay since his death in 1955.
