Cynthia Rodriguez is cheating on baseball star Alex Rodriguez with bad-boy rocker Lenny Kravitz according Perez Hilton. Earlier this week rumors were abound of a late night affair between A-Rod and material girl Madonna.

Sources reveal exclusively to PerezHilton.com that Rodriguez’s wife, Cynthia, has left him.

And, what more, she already has another man!

“Cynthia has been seeing Lenny Kravitz,” an insider reveals exclusively to us.

Damn! Lenny Kravitz!

In fact, a source tells us that Cynthia has left her kids in Miami to go on a romantic getaway with Lenny in Paris, where the two are currently holed up.

“Alex is in New York with the Yankees and Cynthia has left their kids to go be with Lenny - not cool,” says a family friend.

Alex married Cynthia Scurtis in November of 2002. They have two children, Natasha Alexander and Ella Alexander, together. Ella was just born April 21, 2008.

Cynthia had stood by Alex’s side the past couple of years despite rumors of several affairs.  Last year Alex was photographed out and about in Toronto with stripper Joslyn Morse.

It was reported just yesterday that Alex and Cynthia had separated.

Earlier this year Cynthia took several shots at A-Rod during an interview with the Yes! Network.
