A-Rod Author: "He Fell In Love With Madonna"

He doesn't have a hole in his swing, but Alex Rodriguez might have had a hole in his heart vacated after his relationship with Madonna fizzled last year, according to the author of a  salicious new biography about the three-time MVP.

"He fell in love with Madonna," Sports Illustrated writer Selena Roberts told Fox And Friends Tuesday. "It changed his entire life -- he went from a family man to Madonna's boyfriend."

Roberts said the third baseman's infatuation with the singer was based on a longtime admiration he had for her and her music as a kid growing up in South Florida.

The book, which hit stores Monday, also chronicles the slugger's alleged longtime use of steroids and insatiable sexual appetite.
