Evan Peters recalls moment he 'accidentally' flashed Jessica Lange - WATCH

Evan Peters hasn't been afraid of showing some skin on Ryan Murphy's American Horror Story but it seems the X-Men star has been showing more than that backstage. Appearing on Conan on Tuesday, he recalled how he 'accidentally' flashed his junk to co-star Jessica Lange without ever knowing it. "Wow, this is terrible," Peter told O'Brien. "I basically leaned over Jessica Lange's desk in a hospital gown, bare-ass, so I put a c*ck sock on." O'Brien briefly explained what a c*ck sock was before Peters continued explaining the embarrassing moment. "I put it on, and we did the scene, and afterward, Sarah [Paulson] comes up to me, kisses me on the cheek, and is like, 'Oh, Sweetheart, it's OK.'" "And I was like, 'What was I that bad?' And I look over and Ms. Lange is telling the PA that apparently my balls were in her face the whole shot. Apparently a c*ck sock is not just a c*ck sock, it's a c*ck and ball sock." "So lesson learned. You've got to swoop down and sheathe the balls as well," he adds.
