I'll add that the title of the song supposedly written for her is "Le rouge à lèvres sur une cochonne" and though it seems to mean "lipstick on a pig", it's a double entendre. We don't use the feminine word to mean a pig, we use the masculine "cochon" or "porc". A "cochonne" is used to mean "dirty little girl" (kind of eating with her fingers and smearing chocolate all over her face) but about a grown up woman, it's used pejoratively to mean "a woman who likes sex"
