Rapper 50 Cent is suing Taco Bell claiming the US fast food chain has used his name and image without permission in an advertising campaign.
New York court papers say the advert features the star, real name Curtis Jackson, being encouraged to change his name to 79 Cent, 89 Cent or 99 Cent.
The rapper is accusing the chain of "diluting the value of his good name".
The advertisement is part of Taco Bell's "Why Pay More?" campaign, which promotes items for under a dollar.
50 Cent also accuses Taco Bell of employing a guerrilla advertising campaign to fool consumers into thinking he had endorsed the chain.
The lawsuit says the Mexican-themed chain sent a letter to media organisations encouraging the rapper to change his name for one day to promote its advertising campaign.
The letter said that, if the star agreed, Taco Bell would donate $10,000 (£5,000) to the charity of his choice.
