Singer Rihanna has taken her father to court in the US, accusing him of exploiting her name to further his entertainment business.
She claims her father, Ronald Fenty, and his business partner have falsely suggested that she is connected to their firm, Fenty Entertainment.
Their conduct has misled the public and hurt her Fenty brand, the name of her beauty business, the lawsuit says.
Fenty Entertainment did not immediately respond to a request for comment.
Rihanna has asked the court to bar the firm from using the Fenty name for business.
The lawsuit says Rihanna owns trademarks in the US for the Fenty name and has sent formal "cease and desist" requests.
"Defendants continue to this date to use their misrepresentations for their commercial advantage and to mislead the public," it says.
"This fraudulent conduct harms not only plaintiffs but the public at large and requires judicial intervention."
