Say adviser bilked singer

MARC ANTHONY got robbed blind by one of his money managers — to the tune of at least $2.5 million, according to a report.

Accountant Kyle Tessiero secretly siphoned the mountain of cash from Anthony’s accounts over the last eight years without the Grammy-winning singer even noticing, TMZ.com reported Friday.

Tessiero started helping himself to Anthony’s eye-popping wealth about two years after he took a job in 2007 with a prominent New York accounting firm that also counts Drake and Pharrell among its starstudded clients, the website said.

He made unauthorized purchases with one of Anthony’s credit cards and also used the singer’s funds to pay down a $2.5 million tab on his own American Express account, according to a complaint obtained by the Daily News.

The complaint does not specifically name Anthony as the victim, but sources told TMZ the salsa superstar learned about Tessiero’s wild spending sprees last summer after an internal audit.

Tessiero was arrested Aug. 21 and charged with first-degree grand larceny, court records show.
