I really, really wanted to ignore this, but US Weekly has run with yesterday's baseless, unsubstantiated rumor from OK! Magazine and made it… well, slightly substantiated.  It's a rumor that's so powerful and potentially untruthy that people can only say it in the form of a question: are Alex Rodriguez and Madonna engaging in the grotesquely muscled low-body-fat sex of the uber-wealthy?  The answer is a definitive… maybe.

A source tells Us that the $28-million-a-year Rodriguez, 32, has made numerous solo nighttime visits to Madonna, 49, at her spacious home and would sneak out "as late as midnight." Says the source, "All the doormen are talking."

Rodriguez attended Madonna's April 30 NYC concert; the singer sat in his seats at a Yankees game on June 22 (it was the first time she ever was photographed at a Yankees game).

Even though it seems impossible that a good-looking, wealthy man like A-Rod — or anyone with eyes — would be attracted to Madonna, this rumor seems to have some traction because A-Rod supposedly digs muscular chicks, and gossipy people like talking about the Jose Canseco connection.  I think it makes perfect sense.  Gay men LOVE Madonna.
