Alex Rodriguez and Madonna may have more in common than Kabbalah -- a new report says the Yankee is shelling out some serious cash to her charity, Raising Malawi.

The baseballer has been generous with his million-dollar fortune. He gifted $3.9 million to the University of Miami to help build a baseball stadium -- and reportedly didn't want his name on it.

His wife Cynthia has filed for divorce in what is expected to be one of the costliest celeb divorces ever.
