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 also argues that Fenty Entertainment attempted to book a 15-date Rihanna tour in South America, plus concerts in Los Angeles and Las Vegas, without her permission.
The suit is seeking a legal injunction on the use of the Fenty name, as well as unspecified damages. Ronald Fenty has not commented on the action.
