No, she's not called the Material Girl for nothing.

Singer/actress/thang Madonna has filed $2.5 million lawsuit against a New York financial firm, charging it gave her bad advice and left her open to a seven-figure state income tax bill.

The action was filed Tuesday in the Big Apple. It accuses Padell, Nadell, Fine, Weinberger & Co. of malpractice and breach of contract.

At issue is a $2 million tax bill Madonna was levied by New York state officials for 1992, the firm's Bert Padell told the Associated Press. The company had prepared papers saying the jet-set Madonna was a California resident that year.

"[But] the state came in and said she was a New York state resident because she lived here [in New York] more than 183 days" in 1992, Padell said.

The M One paid, but presumably was not amused. She dismissed Padell, et. al, in 1996.

Padell, at least, bears no grudge: She "is a good person. I have no malice toward her," he told the wire service.

Madonna's suit seeks $2 million in compensatory damages and $500,000 in punitive damages.
