Gaga gets even

That’s no way to treat a Lady!

Lady Gaga is firing back against the ex-flame who’s accused her of cheating him out of millions — charging he’s the one who took advantage of her.

In papers filed in Manhattan Supreme Court, Stefani Joanne Germanotta — better known as Lady Gaga — says producer Robert Fusari “induced” her into an “unlawful arrangement” where he would receive 20 percent of the earnings from her first four albums as well as producer fees, even if he didn’t produce the records.

The “Poker Face” singer is seeking a court order declaring their contract “void and unenforceable,” as well as the return of any cash he’s already collected.

While Fusari painted himself as Gaga’s mentor and lover in his lawsuit, her court papers characterize him as an “unlawful employment agent.”

It cites several laws enacted to protect employees “including inexperienced recording artists” from “predatory and financial abusive practices by employment agencies.”

Fusari’s lawyer, Robert Meloni, said: “That argument is one of the most ridiculous I’ve heard in 30 years.”

Meloni said the statute is aimed at barring unlicensed talent agents from collecting commissions from artists, but argued that his client isn’t a talent agent.

“If there was anything to this, any lawyer or producer who ever shopped an artist [to a record company] would be quaking in their boots,” he said. He called the contention “ludicrous” and said it “smacks of desperation.”

Gaga’s lawyers did not return calls for comment.

Fusari’s production company sued Gaga’s production companies earlier this week for $30 million. The filing recounted the professional and romantic history with the songstress he says he helped transform into a superstar.

Meanwhile, a former pal of the singer told The Post she never knew the two were lovers.

“I didn’t know he was dating her,” said Cricket Casey, who called the revelation “kind of creepy” because of the age difference between the pair — she was 20 at the time and he was 38.
