Singer turned mogul Rihanna takes her businesses seriously — so much so, apparently even family members are not immune in her quest to protect her brand.

According to ABC News, the "Diamonds" singer filed a lawsuit against her father, Ronald Fenty, on Tuesday. The suit claims Ronald and his business partner dishonestly implied that his company, Fenty Entertainment, works directly with his superstar daughter. 

Born Robyn Rihanna Fenty, the Grammy-winning songstress has created a lucrative brand around her surname, starting with the highly successful makeup line Fenty Beauty before expanding into lingerie with her brand Savage X Fenty. 

Per the New York Daily News, Rihanna trademarked the Fenty name for her business endeavors in 2012. This means even though her father was a Fenty first, he is not allowed to use the name for business ventures. In the suit, the "Rude Boy" crooner alleges Ronald and his partners duped fans and customers into thinking Fenty Entertainment is an arm of the Rihanna empire.

"Although Mr. Fenty is Rihanna’s father, he does not have, and never has had, authority to act on Rihanna’s behalf, nor has he ever been authorized to use her name, intellectual property or publicity rights," the suit states. 

Rihanna has reportedly made numerous attempts to stop her father outside of the courts; these efforts included sending him cease and desists notifications. Newsweek reports these overtures all went unanswered, leaving the artist feeling as if she had no choice but to pursue the matter before a judge.

Besides seeking to close down Fenty Entertainment, Rihanna is also pursuing unspecified compensation. Ronald has yet to comment on the situation.
