A quick google returns songs called "Damn Girl" by Justin Timberlake, All American Rejects... I think it's safe to say that it's just a well known phrase, not a reference to a song called "Sexy Bitch".
Actually, both those songs have misogynistic lyrics too. The JT song includes the line "Don't need no L'Oreal 'cause bitch you're bad as hell." Maybe referring to women as "girl" is just a bad jump-off point.
The point I was making was that there is no reference to any of these songs in the article title. It's a commonly used phrase- including by women themselves.
