Madonna to Joe Francis -- Relax, I'm Not Singing Your Stupid Song 'Girls Gone Wild' At Super Bowl

Joe Francis is flattering himself by thinking Madonna will sing her new song, "Girls Gone Wild," during the Super Bowl halftime show ... so says Madonna's rep.

As TMZ first reported, Francis had his lawyers fire off a letter to Madonna demanding she negotiate a licensing agreement for using his infamous trademark in her song ... and also insisting she NOT sing the new track during Sunday's performance.

But a rep for Madonna tells TheWrap the song is not part of her set list.

But the matter isn't settled ... because Joe's lawyer wants money from Madonna for putting the song in her album.
