OMG! This could be the reason that Madonna has secured a high-profile British divorce attorney.

Us Magazine is reporting that the Material Girl has been spending late nights with baseball whore Alex Rodriguez.

The magazine's sources say that Rodriguez has been spotted leaving as late as midnight!

Rodriguez, was evidently at Madonna's Central Park West apartment in New York City shortly after his wife gave birth to their second daughter.

Meanwhile - Madonna's hubby, Guy Ritchie, was in the U.K.

Guy arrived in New York on Monday without a wedding ring and with a miserable look on his face.

Can Madonna and Guy work it out?
