According to the NY Daily News, when A-Rod’s estranged wife, Cynthia Rodriguez, found out her man was cheating on her with Madonna, she ran up a $100K tab on his credit card!

Alex Rodriguez’s bitter divorce took an ugly turn on Monday night when Team A-Rod accused his estranged wife of going on a spiteful spending spree in Paris last weekend. Spurned spouse Cynthia Rodriguez used the Yankee slugger’s credit card to the tune of $100,000 to punish him for a dalliance with Madonna that both he and the Material Girl deny, an A-Rod pal said.

“She’s been spending wildly,” the friend said. “She spent close to $100,000 on her jaunt to Paris.”

Cynthia flew the godparents of her daughters, Dodd and Sabina Romero, and their older daughter, first-class to the City of Light, the friend said.

There, Cynthia “had spa treatments, she went to the best restaurants”

All I can say is, it serves him right.
