Yeah I think she knew the theme's behind the song and I think even if she did know them she would have sung the song. I mean Mylene and Espire (
) had just made her a hit in France with Moi Lolita and her first album and now she wanted her to sing a suggestive song on the next album, so what! This is Mylene Farmer and she started your career not to mention is writing your next album which will probably be a big hit too. It is a great sounding song with some mysterious and suggestive theme's, Mylene is know for that. Who would pass up a opportunity like that? Alizée felt she wasn't sacrificing her dignity or image to do the dancing or sing the song, she doesn't mind being sexy. As implied by, "In any case, being sexy includes being natural. Anything can be sexy, except vulgarity." I would also imagine there could have been a contract of some kind still in effect from the Gourmandises era.
