Madonna & A-Rod: More Than Friends?

On June 25, Rocco Ritchie happily romped in the grass at NYC's Central Park dressed in a New York Yankees baseball cap and shirt. Perhaps he got his outfit from his mom Madonna's friend, NY Yankee star Alex Rodriguez!

Amid rumors that her marriage to hubby Guy Ritchie is on the rocks, OK! has learned that the Material Girl has been spending a lot of time with the married A-Rod, finding solace in the handsome third baseman as her marriage to the british director fizzles.

One thing this pair has in common is their love of a good workout! 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.

While nothing has been confirmed about the state of their marriage, one thing is undeniably clear--Madonna and hubby Guy have not been seen together in months. And although he did accompany his wife to Cannes, witnesses say his demeanor looked strained while Madonna seemed to be having the time of her life.

The couple is rumored to own multiple properties in London, NYC and the English countryside, but this past April, the singer bought a new $7 million apartment--directly upstairs from her current Upper West Side home--and purchased it in her maiden name, Madonna Ciccone!

While Rodriguez's rep had no comment about the nature of his relationship with Madonna, the singer's rep tells OK!, "They met briefly at a charity event and that's it." As for whether the singer and Guy Ritchie are headed for divorce court, her rep tells OK!, "No comment at this time is all I'm prepared to say now."
