Katy: Yes, I did kiss a girl once

Singer Katy Perry has revealed that she really did once kiss another girl - and liked it. The 23-year-old old Californian musician's single I Kissed A Girl has celebrated more than five million worldwide sales. Now, in an interview with OK! magazine, she has told of her experience as a teenager. Perry is asked if she really had kissed a girl. She replies: "Of course. I think I was 19. I kissed a girl and it was great." She says it went no further and she did not write the song about that one experience or person. She adds her boyfriend understands the "tongue-in-cheek" aspect of the song.
