Matt Damon admitted he was aware that Harvey Weinstein sexually harassed Gwyneth Paltrow years ago, calling the fallen film mogul an “a–hole” and “womanizer.”

Damon, who co-starred in the Weinstein-produced “The Talented Mr. Ripley” in 1999 with Paltrow, said he learned of her allegations through his friend Ben Affleck.

“I knew the story about Gwyneth from Ben because he was with her after Brad [Pitt], so I knew that story,” Damon said Monday on ABC News. “I never talked to Gwyneth about it, Ben told me. But I knew that they had come to whatever, you know, agreement or understanding that they had come to, she had handled it. She was, you know, the first lady of Miramax. And he treated her incredibly respectfully.”

Weinstein, who back then headed Miramax Films, was proud of his bad-boy rap in Hollywood.

“So people say, ‘everybody knew,’ like, yeah I knew,” Damon explained. “I knew he was an a–hole, he was proud of that. That’s how he carried himself. I knew he was a womanizer. I wouldn’t want to be married to the guy. But the criminal sexual predation is not something that I ever thought was going on. Absolutely not.”

Damon, who got his big break in Hollywood starring alongside Affleck in the Miramax-produced “Good Will Hunting,” said Weinstein hooked him up with a three-movie deal but that he never worked with him again after that.

“You had to spend about five minutes with him to know that he was a bully. He was intimidating,” Damon said. “Miramax was the place, really the place, that was making great stuff in the ’90s. And it was like, ‘Could you survive Harvey?'”

Meanwhile, George Clooney, who appeared on ABC with Damon to promote their new movie “Suburbicon,” said Weinstein often bragged about his dalliances with his colleagues.

“Harvey would talk to me about women that he’d had affairs with. I didn’t necessarily believe him, quite honestly, because to believe him would be to believe kind of the worst of some actresses who were friends of mine,” said Clooney, who worked with Weinstein on 1996’s “From Dusk Till Dawn.”

Clooney added, “But the idea that this predator, this assaulter was out there silencing women like that, it’s beyond infuriating.”
