Rapper T-Pain has filed suit against the bosses of an auto-tune effect firm over allegations they illegally used his image and likeness to sell their products.
The "I'm Sprung" hitmaker has used the pitch correction software extensively throughout his career and previously teamed up with Antares to promote its auto-tune items.
That deal ended in June and T-Pain went on to form a new collaboration with rival firm Izotope to create his own range of sound effects, called The T-Pain Effect.
But the hip-hop star claims Antares executives have continued to illegally use his fame to boost sales of its products - and he's demanding at least $1 million in damages, reports AllHipHop.com.
He is also asking a California judge to issue an injunction preventing Antares from using anything that could connect T-Pain to the company's auto-tune devices, claiming it could substantially damage sales of his new Izotope products.
