Madonna has been hosting late-night visits from New York Yankee Alex Rodriguez at her Central Park West apartment in New York City, Us Weekly reports.
A source tells Us that the $28-million-a-year Rodriguez, 32, has made numerous solo nighttime visits to Madonna, 49, and would sneak out "as late as midnight."
People magazine, however, got a statement from Liz Rosenberg, Madonna's spokeswoman, saying: "Madonna's husband Guy [Ritchie] 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."
Rosenberg also explained the A-Rod friendship, saying: "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."
Rodriguez attended Madonna's April 30 concert in New York; 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.
Rodriguez, 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.
Ritchie, 39, arrived in New York City from London on Monday after several weeks apart from his family.
Madonna has been in New York since the Times of London reported that she consulted the same high-profile divorce attorney who worked with Paul McCartney and Prince Charles. Us reports that Ritchie has also sought legal advice from Forsters law firm in London.
It is believed that the couple, who wed in 2000, did not have a prenup, according to The Times. Madonna is worth an estimated $600 million.
Ritchie's mother, Lady Amber Leighton, denied any split rumors in an interview with London's Mail on Sunday.
"They are no different to most other couples and we all know that being together can be hard sometimes and marriages are not always a bed of roses," she said.
In other news, a weekend fire that destroyed a childhood home of Madonna has been deemed suspicious by arson investigators.
The Oakland County Sheriff's Arson Unit and the Rochester Hills Fire Department are investigating the Friday night blaze.
A passer-by had noticed flames coming out of the unoccupied house in the Detroit suburb of Rochester Hills and called the fire department.
Rochester Hills Fire Chief Ron Crowell told The Detroit News and Detroit Free Press the fire appears to have started in the living room area. He said it caused extensive smoke and fire damage throughout the two-story brick house.
Madonna, known then as Madonna Louise Ciccone, spent some of her younger years as one of six siblings living in the home.
