A songwriter and music producer who claims he helped launch pop star Lady Gaga says she squeezed him out of her lucrative career after he co-wrote some of her songs, came up with her stage name and helped get her record deal. Rob Fusari filed a $30.5 million lawsuit against the Grammy Award-winning performer, saying his protege and former girlfriend ditched him as her career soared. “All business is personal,” said the lawsuit, filed Wednesday in a Manhattan state court. Fusari had credits on such hits as Will Smith's “Wild, Wild West” and Destiny's Child's “Bootylicious” when a friend steered the piano-playing singer to him in March 2006, according to his lawsuit. According to the lawsuit, Lady Gaga and Fusari's relationship turned romantic and then became a business partnership in May 2006, when they created a joint venture to promote her career.
