f(x) member Krystal revealed that the first time she watched an R-rated movie was with Girls’ Generation.

Krystal and her fellow member Sulli appeared as guests on the August 21 installment of MBC’s ‘Radio Star’. During the show, the show’s MC asked whether it was true Girls’ Generation forced her to watch an erotic movie.

Krystal explained that it happened rather naturally as they were already watching the movie when she came. She said, “I went to visit the unnis, and they were just watching the movie. Not everyone was there, but the ones who were were all older than me. I tried to leave because there was a sex scene but they called me back in. It was really embarrassing.”

Sulli also talked about her first encounter with such movies and revealed it was too much for her to handle when she first watched one.
