As Madonna and husband Guy Ritchie stepped out holding hands Tuesday amid reports of a potential split, Kravitz and Rodriguez's wife Cynthia have been "spending cozy time" in Paris for at least the past four days, the paper reports.

Us Weekly reports in its new issue, on newsstands now, that Madonna has also been hosting late-night visits from Rodriguez, 32, at her apartment.

Cynthia and Alex Rodriguez - who wed in 2002 and have two young daughters - attended NBC's New Year's Eve 2008 party where Kravitz performed.

Madonna, 49, and Kravitz, 44, collaborated on her 1990 hit "Justify My Love." The pair were romantically linked at the time.

Another connection? Rodriguez, Madonna, and Kravitz all have the same manager: Guy Oseary.

Oseary sat in Rodriguez's seats at a Yankees game with Madonna and her kids on June 22.

Kravitz attended Madonna's private showcase of her latest album, Hard Candy, in Paris on May 6. He also joined the Material Girl on stage for a performance of her song "I Love New York" in Paris in September 2006.

Meanwhile, a source tells Us Weekly that Madonna and Rodriguez's relationship grew so close that he possibly visited her as early as the night after his wife Cynthia gave birth to their second child in April.
