from www.tmz.com – Joe Francis — the mastermind behind “Girls Gone Wild” — is sending Madonna a cease and desist letter, threatening that he’ll take legal action if she sings the song from her new album — titled “Girls Gone Wild” — at the Super Bowl.

TMZ has obtained the letter that Francis has sent to Madonna and her “co-conspirators.” Francis’ lawyer threatens to sue all of them for attempting to get a “free ride on the valuable consumer goodwill and brand recognition” of Joe’s famous trademark.

Francis’ lawyer makes it clear: “Your misappropriation of my clients’ trademark will not be tolerated.”

But Francis is willing to cut a deal with Madonna, provided she agrees to the following terms:

— Negotiate an immediate licensing agreement for the use of Joe’s trademark
— Account for the number of times Madonna has already used the trademark
— NOT PERFORM THE SONG AT THE SUPER BOWL

Joe thinks NBC and the NFL are conspiring with Madonna, so the letter went to them as well.

Joe’s lawyer is demanding a response by 5 PM PT today … or else.
