The Lost Boys actors, now 36, mentioned the incidents during an argument on their US reality show The Two Coreys.
Haim is heard telling Feldman: "You let me get f**cked around in my life. Raped, so to speak, when I was 14 and a half, by a guy you still hang out with.
"What did you think when you saw that s**t going on with me?"
Feldman replied: "I was being molested at the same time by someone else. What did you do?"
The second season of The Two Coreys is currently airing in the US.
