Producer Rob Fusari has filed a $35 million lawsuit against singer Lady Gaga alleging that she dumped him as soon as she became a star.

The producer claimed that he helped Lady Gaga launch her career as he was instrumental in landing her a deal with record label Interscope, reports dailystar.co.uk.

Fusari, who worked with the singer on her debut album 'The Fame', reveals that his working relationship with the star soured after she ditched him upon gaining global recognition.

Fusari filed the lawsuit against the singer in New York.
