What is up with these rumors that Madonna and Alex Rodriguez have been gettin' it on?   Even Keith Olberman is talking about it!   OK Magazine breaks it down, noting that these two have been spending a lot of time together.

Last October, Madonna and A-Rod were spotted working up a sweat at Reebok Sports Club NY in Manhattan. Months later, the sports hero attended the singer's charity Raising Malawi, where Madonna reportedly introduced him to her unimpressed 11-year old daughter Lourdes.

Then, in May, A-Rod attended the singer's show at NYC's Roseland Ballroom, and partied with her afterwards at The Box nightclub until early morning.

The New York Daily News reports that the baseball star has made "numerous late-night visits to Madonna's Central Park West apartment" and that he "has been seen arriving alone... and sneaks out of sneaks out of Madge's building 'as late as midnight.'"

Madonna's rep echoes her mother-in-law's exhortations that the singer is not divorcing husband Guy Ritchie... sort of.  "No comment at this time is all I'm prepared to say now."  Well.  We all know what "no comment" means, right?
