By her own account, Mimi Haleyi once rebuffed one of Harvey Weinstein’s relentless advances by telling him, “I hear you have a terrible reputation with women.”

Haleyi says she didn’t know just how terrible the then-revered Hollywood honcho could be until he sexually assaulted her in his New York City apartment in 2006 — an episode she’s expected to detail as a witness Monday at Weinstein’s rape trial.

Weinstein, 67, is charged with forcibly performing oral sex on the former production assistant and raping another woman, an aspiring actress, in a Manhattan hotel room in 2013. He insists any sexual encounters were consensual.
