The 49-year-old actress said in an interview with ABC News that Weinstein "ignored" her protests when he allegedly sexually harassed her in a hotel room during her early career.
Judd was filming the movie Kiss the Girls when Weinstein invited her to a Beverly Hills hotel for "a business appointment." She said the producer asked to give her a massage once she was in the room, then asked for her to give him one.
"I thought no meant no," the star told Diane Sawyer. "I fought with this volley of nos, which he ignored. Who knows, maybe he heard them as 'maybe.' Maybe he heard them as 'yeses.' Maybe they turned him on."
Judd said Weinstein also asked her to watch him take a shower, and that she ultimately offered the producer a deal in order to escape his advances.
"He kept coming back at me with all this other stuff," the actress said. "And finally I just said, 'When I win an Oscar in one of your movies, OK?' And he was like, 'Yeah, when you get nominated.' I said, "No, when I win an Oscar.' And then I just fled."
Judd said she recounted part of her experience to her mom, singer Naomi Judd, who recently encouraged her to come forward. Judd went public in a New York Times report published Oct. 5 detailing multiple instances of Weinstein's alleged abuse and harassment.
"What I'd say to Harvey is I love you and I understand that you're sick... there's help for a guy like you," the actress told Sawyer.
Judd thanked fans for their support Thursday on Twitter, saying coming forward was "the right thing to do."
