Cynthia Rodriguez spent the weekend blowing $100,000 of Alex Rodriguez’ money just before filing for a divorce from the Yankees slugger in a Miami court on Monday.

Cynthia’s wasting no time taking A-Rod to the cleaners, a disgusted pal of the third baseman told the New York Daily News Tuesday. (And you thought the Christie Brinkley-Peter Cook divorce was ugly.) Cynthia flew to Paris and “had spa treatments [and] went to the best restaurants,” courtesy of her estranged hubby’s Mastercard.

“She’s been spending wildly,” the spy said.
