LOS ANGELES, California (X17online) - Yankees star Alex Rodriguez is making a half a million dollar donation to Madonna's charity, Raising Malawi, according to the NY Daily News.

A source told the newspaper, "They've asked him for a million dollars, and I hear he's agreed to give at least $500,000." This isn't the first time Rodriguez has made a large donation; in 2003, he gave $3.9 million to the University of Miami to help build a baseball stadium.

Neither Rodriguez's representative nor a spokesperson for the charity would confirm the donation.

Rumors have run rampant for quite some time that Madonna and Rodriguez were having an affair, which led to his wife Cynthia filing for divorce in early July. Rodriguez's estranged wife even cited Madonna as a reason for the divorce, as well as emotional abandonment, but Madonna and Rodriguez have both denied any romantic involvement.
