I Kissed a Girl
Perry said the song is "about the magical beauty of a woman." Perry told Steppin' Out magazine: "'I Kissed a Girl' was inspired when I opened up a magazine and I saw a picture of Scarlett Johansson ... I was with my boyfriend at the time, and I said to him, 'I'm not going to lie: If Scarlett Johansson walked into the room and wanted to make out with me, I would make out with her. I hope you’re okay with that?'"
