Christine Prody OJ Simpson NEWS

Did O.J. Simpson agree to star in a three-way porn flick in exchange for more than a million bucks? That’s the claim being made in next week’s Globe tabloid, according to both the New York Post and the New York Daily News, but O.J. says it ain’t so. And the Juice’s lawyer, Yale Galanter, tells both papers that his client is being set up a la Frank Gifford — and is threatening to take the magazine to court.

According to the Globe, Simpson took part in a three-way romp with his sometime girlfriend Christine Prody and Playboy and Penthouse model Patty Kuprys in Miami’s fancy Mutiny Hotel (in room 310, to be precise).

In the film, reportedly directed by Peter “Prescription for Lust” Davy, Simpson pleasures each woman four times and then watches them frolic, the Globe maintains. (At a certain point, according to the Globe, Simpson can be heard to sing, “If I Only Had a Brain.”) Cameras were reportedly hidden in plants and light fixtures so it would look like Simpson had no idea what was going on.

But Galanter tells both the Post and the Daily News that he suspects Kuprys was paid by the Globe to set his client up and that, while the Simpson was in the hotel room alone with the two women, they were only drinking a nightcap. The sex part never happened, he says.

“Everybody was completely, 100 percent clothed,” he tells the Post.

What’s more, he tells the Daily News, “there is no videotape of him doing anything explicit.”

At a certain point, Galanter says, O.J. spotted a camera in “the wall or in one of the plants” and took off in a hurry.

The Globe contends that Simpson knew precisely what was going on, and claims to have its hands on a signed contract in which Simpson agrees to collaborate with Davy on “an adult movie.” But Galanter insists that the former football star’s signature was forged.
