Billy Baldwin viciously claps back at Sharon Stone over her ‘Sliver’ sex claims: ‘I have so much dirt on her’

His basic instinct is to fight back.

Billy Baldwin barked at Sharon Stone on social media Tuesday after the actress claimed that producer Robert Evans pushed her to have sex with the actor while they were filming “Sliver” in 1993.

“Not sure why Sharon Stone keep [sic] talking about me all these years later?,” his tirade on X began.

“Does she still have a crush on me or is she still hurt after all these years because I shunned her advances?”

And then Baldwin, brother of Alec Baldwin, became vaguely threatening.

“I have so much dirt on her it would make her head spin but I’ve kept quiet,” he said.

“Wonder if I should write a book and tell the many, many disturbing, kinky and unprofessional tales about Sharon?,” Baldwin, 61, said.

“That might be fun.”

The spat started this week when Stone told Louis Theroux on his podcast that Evans encouraged her to sleep with Baldwin, her co-star, in hopes of improving his onscreen performance in the thriller.

“He called me to his office,” Stone, 66, said of the late producer who was once head of Paramount and produced box office hits such as “The Godfather” and “Love Story.” 

“And he’s running around his office in sunglasses explaining to me that he slept with Ava Gardner and I should sleep with Billy Baldwin, because if I slept with Billy Baldwin, Billy Baldwin’s performance would get better.”

Baldwin wound up being nominated for the Golden Raspberry Award for worst actor for his turn as a video game designer.

She’d previously recounted the incident in her 2021 memoir, “The Beauty of Living Twice,” but didn’t name names at the time.

The actor’s online rant only got angrier.

“The story of the meeting I had with Bob Evans imploring him to allow me to choreograph the final sex scene in the photo below so I wouldn’t have to kiss Sharon is absolute legend,” he wrote.

The actor even roped Janice Dickinson into his fiery missive.

“Did she say to her gal pal Janice Dickinson the day after I screen tested and ran into them on our MGM Grand flight back to New York… ‘I’m gonna make him fall so hard for me, it’s gonna make his head spin.’ ???.”
