The scene could be a flashback from when Gaga's character the Countess was still human. On a recent episode, it was learned that the Countess is a vampire.
While Gaga was busy filming, her fiancé Taylor Kinney was reflecting on the first time they kissed, on "Watch What Happens Live."
He said, "I remember I went up, and we're rolling, and I kissed her and she didn't expect it. They cut, and she slapped me. And then it was just awkward. And then the next take, I just did it again and then she didn't slap me. She didn't slap me then." Watch!
He added, "We had a good time. I think there was chemistry," he said. "I remember it was a late shoot. We were shooting until 4 or 5 in the morning or something like that. We exchanged information. A few weeks went by and we kept in touch, and then that's that."
