Us Weekly reports in its new issue, on newsstands today, that Madonna's seven-year marriage to Guy Ritchie has stalled out – and the singer has been hosting late-night visits from New York Yankee Alex Rodriguez at her Central Park West apartment in New York City. A ringless and grim-faced Ritchie, 39, arrived in New York City from London yesterday after several weeks apart from his family. 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). Her son Rocco, 7, also sported Yankees gear on June 25 while playing in Central Park.
