Lady Gaga is firing back at the music producer is suing her for $30.5 million and claiming that he launched her career. Her lawyer said that the agreement that Gaga and Rob Fusari made was "unlawful."

Fusari filed the lawsuit claiming that Gaga ditched him when she made it big. The lawsuit said they co-wrote songs like "Paparazzi" and "Beautiful, Dirty, Rich" and that he also came up with Gaga's stage name and helped get her record deal.

Lady Gaga and Fusari's relationship turned romantic and then became business partners, when they created Team Love Child to promote her career. Fusari's share was 20 percent.

But Lady Gaga's lawyer said the arrangement was "structured in such a way as to mask its true purpose, which was to provide Fusari unlawful compensation for their services as unlicensed employment agents." The lawyer also explained that Fusari and his company violated laws that prohibited them from "acting as employment agents without a license and charging Lady Gaga an unlawful fee for their purported services."
