You knew it would happen sooner or later! - There's a guy out there claiming he has a sex tape of Madonna and Alex Rodriguez shot just a couple months ago!!!!

The story goes, a friend of his, who's a pal of Madonna's through Kabbalah, offered up her apartment to Madge and her boy toy for their afternoon trysts. When this guy found out, he installed a hidden camera in the living room, with the lens pointed squarely on the sofa.

What went down on that sofa, he claims, is the Material Girl and A-Rod going at it with some "I did not have sexual relations with that woman"-type action.

We started getting emails last week, telling us about the existence of the tape and then asking us to market it for the guy who owned the camera.

But then his brother-in-law started calling around to the UK tabs and one of them - the Daily Mirror - offered him $2 million for the tape.

I've seen what I believe to be the email from the Mirror but I've still never seen the tape!!!

So to Madonna and her peeps ... I'm not claiming this tape is real or that it even exists, I'm just saying this guy seems pretty damn serious about it and so do certain members of the media (we'd already had calls from other UK outlets, asking us to alert them as soon as we got our hands on the tape).

Do you believe it? Will video of Madge and her Rod ever see the light of day???
