According to a bombshell report by The National ENQUIRER, the disgraced HIV-positive actor corrupted his much younger Lucas costar on set with drugs, then had anal sex with him. Sheen was 19 at the time, while Haim was barely a teenager.
Then, after the nonconsensual sex act, Sheen cruelly rejected his alleged victim, Haim's close pal claimed.
"Haim told me he had sex with Sheen when they filmed Lucas," Dominick Brascia, a former actor and a close friend of Haim, told The ENQUIRER. "He told me they smoked pot and had sex. He said they had anal sex. Haim said after it happened Sheen became very cold and rejected him. When Corey wanted to fool around again, Charlie was not interested."'
Years later, the two reportedly had sex again when they were both in their 20's.
"Haim told me he had sex with Sheen again," claimed Brascia. "He claimed he didn't like it and was finally over Sheen. He said Charlie was a loser."
Brascia's horrifying account matches those of dozens of other sources who also told The ENQUIRER that Haim named Sheen, now 52, as his abuser before his 2010 death from pneumonia at just 38.
"Corey was so confused by the sexual encounter he believed, like so many victims, he was 'in love' with his abuser," another source told The ENQUIRER, adding that in reality it was Sheen who pressured the much-younger teen into a sexual relationship.
Actor and filmmaker Corey Feldman, 46, has claimed he and his longtime best friend were sexually abused by men in Hollywood — and even said in his 2013 memoir Haim was told by a man while filming Lucas that "it was perfectly normal for older men and younger boys in the business to have sexual relations."
While he didn't name any names in his book, he did claim in a later interview that he was "not a huge fan" of Sheen. He cryptically claimed: "He's affected other people that I know."
Feldman said his former pal "fought for his entire life to recover from those early experiences and to get his life together."
In their divorce papers, Charlie Sheen's ex-wife Denise Richards, 46, claimed she'd caught him looking at gruesome pornography featuring boys and girls who looked to be underage.
While Sheen has never spoken out about his relationship with Haim, a source close to the star said "there's no doubt in my mind that something went down…enough that he had a grudge against Haim forever."
