It's not like he's going to admit it!

Charlie Sheen is denying he raped a then 13-year-old Corey Haim on the set of their movie Lucas back in the 80s, after The National Enquirer published their bombshell report on Wednesday.

"Charlie Sheen categorically denies these allegations," Sheen's rep told The Hollywood Reporter.

The gossip rag seems pretty certain about their claims, and we doubt they'd put something like this out there without thinking they could be sued if it's false.

"Haim told me he had sex with Sheen when they filmed Lucas," Dominick Brascia, a former actor and a close friend of the Lost Boys legend, exclusively 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."

The two allegedly romped again when Haim was in his late 20s.

"Haim told me he had sex with Sheen again. He claimed he didn't like it and was finally over Sheen. He said Charlie was a loser," Brascia added.

The mag says that Brascia is just one of more than 100 people who can corroborate the story. One of Sheen's closest confidantes spoke to the Enquirer on a condition of anonymity and admitted that the TV star had copped to having sex with Haim, but insisted it was consensual.

Haim's close pal Corey Feldman hinted at all of this in his 2013 tell-all memoir, but didn't name Sheen directly for fear of retaliation.

"At some point during the filming [of 'Lucas,' Haim] explained an adult male convinced him it was perfectly normal for older men and younger boys in the business to have sexual relations, that it was 'what all guys do.' So they walked off to a secluded area between two trailers during a lunch break for the cast and crew, and Haim, innocent and ambitious as he was, allowed himself to be sodomized," he wrote.

This whole story is so disturbing.
