Rosie O'Donnell is calling out Kevin Spacey for allegedly having a rep as a predator in Hollywood, akin to Harvey Weinstein ... saying everyone in Hollywood knew.
Rosie took to Twitter Monday to directly slam Spacey for not remembering an alleged attempt at molesting then-14-year-old Anthony Rapp ... and she didn't mince words.
As we reported ... Spacey came out as gay in his statement addressing Rapp's allegations. Other celebs have blasted him for choosing such a moment to embrace his sexuality.
Kevin hasn't responded to the latest criticism.
