The producer who claimed he’d been stiffed by Lady Gaga is getting sued for allegedly stiffing his lawyer.

In papers filed in Manhattan, the law firm of Meloni and McCaffrey said it represented Rob Fusari in his legal battle against his former protégée, only to be let go shortly before both sides worked out a settlement.

Fusari has paid Meloni only about $15,000 of his $47,000 tab, according to the suit. He declined comment.

Fusari and the firm filed the $30 million lawsuit against Gaga last year, charging that he transformed Stephanie Germanotta into a star and even came up with her stage name, then was stiffed on royalties.

Gaga filed a countersuit, charging that Fusari had taken advantage of her business naivete by signing her to an unfair, and illegal, deal.
