Us Weekly reports that Madonna’s seven year marriage to director Guy Ritchie is on the fritz because the singer has been spending a lot of time with her NY Yankee ‘friend,’ Alex Rodriguez, at her Central Park West apartment in New York City.

Here are the mag’s details:

– Rodriguez, who makes $28 million/year, has been meeting Madonna at her NYC home and would sneak out “as late as midnight,” said a source. “All the doormen are talking.”

– Rodriguez attended Madonna’s April 30th NYC concert

– Madonna, 49, sat in Rodriguez’ seats at a Yankees game on June 22nd (it was her first time getting photographed at a Yankees game)

– Rodriguez, 32, married with two young daughters, has already faced speculation about cheating: In 2007, he and a stripper were reportedly spied in Toronto, Miami and Dallas.

FYI: A ringless Guy Ritchie, 39, arrived in New York City from London yesterday after almost a month apart from his family.

Madonna’s rep, Liz Rosenberg, has recently shot down these rumors, telling People magazine,

“Madonna’s husband Guy arrived in New York last night to be with his wife and family–not in a last ditch attempt to save his marriage which does not need saving. There are no plans for Madonna and Guy to divorce.”

She continues, “Madonna and Alex have the same manager, Guy Oseary. They have met. They know each other and Madonna took her kids to a Yankees game last week. There’s really not anything to comment on beyond that. It’s nothing new that people are airing tons of dirty laundry Madonna’s way lately – much of it untrue.”

Rosenberg jokes, “By the way, rumors of Madonna and Lil Wayne are quite exaggerated, as well.”

Do you think Madonna is cheating on her Guy?
