The “Basic Instinct” star divulged that Robert Evans wanted her to get intimate with Billy Baldwin while they filmed 1993’s “Sliver.”

“He called me to his office. He had these very low ’70s, ’80s couches, so I’m essentially sitting on the floor, when I should have been on set,” Stone said on the “Louis Theroux” podcast Monday.

“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, and we needed Billy to get better in the movie because that was the problem.”
