Emma Roberts is kissing and telling.

The American Horror Story star revealed what it was really like to lock lips with Kim Kardashian in the AHS: Delicate Part Two series.

"You know, we do it, you forget about it, and seeing it, it looked so intense," Emma told Jimmy Fallon on the April 3 episode of The Tonight Show. "But meanwhile, we were laughing, because we kissed and they said, 'Cut,' and Kim looked at me and started laughing. I was like, 'What?' and I just had her [lip] gloss all over my face."
