Sultan of sleaze Joe Francis is threatening to sue Madonna if she performs her new song called “Girls Gone Wild” at the Super Bowl tomorrow. Yes, really.

Francis, creator of the infamous Girls Gone Wild franchise, in which he films drunk girls exposing themselves on spring break, is apparently dead serious.

He has issued a cease and desist letter claiming he will take legal action against Madonna if she sings that particular song at this weekend’s festivities.

The letter (sent to Madonna, NBC Universal and NFL Commissioner Roger Goodell) from Francis’ Nevada lawyer David Houston, states that:

“[Francis] became aware of Madonna’s new track based on the presales of her , as the #1 song on the album is ‘Girls Gone Wild.’”

“Mr. Francis and Girls Gone Wild have worked tirelessly for an excess of two decades to build his brand and to protect his trademark Girls Gone Wild.”

“Girls Gone Wild’s trade identity and trademark are both extremely valuable assets which my client must protect vigorously,” the letter continues.

The letter claims Madonna has “violated Federal and State trademark laws by making unauthorized use of Mr. Francis’ trademark Girls Gone Wild.”

For what it’s worth, it looks like she wasn’t going to sing it anyway.

Madonna’s set list reportedly includes “,” “Ray of Light” and “Vogue,” along with “Music” and “Holiday.” No GGW action.

regarding the set list, “That would be a wise choice on her part.” Good luck getting it off the album and iTunes, though.

It’s been nearly two weeks since she was rushed to the hospital after going into convulsions, however whereabouts following her emergency visit to a Los Angeles, CA medical facility are still unknown.

While speculation over the location of her recovery has had the Internet abuzz, friends of the 49-year-old are staying mum. telling People, “Demi is such a private person and where she is now is being kept top secret,” while another pal added that only a “very close” circle of the star’s friends know where she’s currently residing.

Several reports claim Moore is undergoing “spiritual counseling,” while others suggest that she’s being treated at the Cirque Lodge in Sundance, Utah.

Despite the rumors, the only confirmation Demi’s camp has given since her medical emergency is that she was seeking “professional assistance to treat her exhaustion and improve her overall health.”
