During a new episode of his show, the 65-year-old actor recalled filming a scene with the 34-year-old hitmaker, when the two worked together on Ryan Murphy's hit FX series.
"I can tell when I meet you, within three minutes, how you were raised. When I met Lady Gaga on the American Horror set... beautifully brought up," he shared. "'Please, thank you.' Lovely girl."
However, the star went on to explain GaGa's interesting approach to acting, which came to light when they rehearsed a scene in which her character murders his.
"We had a scene where she was gonna blow fairy dust in my face, and then knock me down, and blind me, chase me, and then roll me over, kick me," Leslie explained. "And then she was supposed to squat down on me and cut me with a knife."
He continued: "She took me in the woods right before we shot," and she said, "You know, I tend to sexualise all my acting partners". I thought, "Where's this going?."
"Well honey, she kicked me, rolled me over, and got down on me and started riding me... I didn't know what I was supposed to do! I just laid there and thought, 'How do I get myself into these situations?'."
