Emma Roberts talks kissing Kim Kardashian on 'American Horror Story'

Emma Roberts is opening up about a high-profile smooch.

Appearing recently on "The Tonight Show Starring Jimmy Fallon," Roberts told the host about kissing co-star Kim Kardashian on "American Horror Story: Delicate Part Two."

"It's kind of like another day at the office," she said to Fallon.

Fallon agreed with her, saying, "you can't just kiss Kim Kardashian and not tell everybody."

"You forget about it and then seeing it, it looked so intense. But meanwhile we were laughing because we kissed and they said cut, and Kim looked at me and started laughing," Roberts revealed. "I was like, 'What?' And I just had her [lip] gloss all over my face. So, we had to do major cleanup in between every take because she had the most perfect glossed lips, obviously. And it was everywhere."

"American Horror Story: Delicate Part Two" airs Wednesdays on FX.
