Mariah Carey's older brother is reportedly suing the singer for defamation and "emotional distress" over the contents of her recently published memoir, The Meaning Of Mariah Carey.
Morgan Carey is said to be seeking unspecified damages against the music icon, claiming that the book falsely suggests he was violent.
He says he has suffered "extreme mental anguish" and "serious damage to his reputation" as a result of the book, which was published in September of last year.
Morgan claims that he is suing over scenes in the memoir which allege that he had a "vicious fight" with his father when Mariah was a child.
In the book, the singer claims that it took "12 cops to pull my brother and father apart" but Morgan says that the incident was "fictional".
He is also reported to be suing over the sections of the book which he claims implied that he tried to extort money from Mariah after her rise to worldwide success, and that he had been "in the [criminal justice] system".
"[Morgan] brings this action more in sorrow and disappointment in his sister's betrayals and malicious falsehoods than in anger at them," papers filed in court claim.
The suit, which has been filed in Manhattan, also names the book's co-author Michaela Angela Davis, its publisher Macmillan, and the imprint Andy Cohen Books as co-defendants.
Mariah’s sister, Alison, is also suing the singer for $1.25 million over the memoir.
She claims that Mariah wished to "humiliate and embarrass her" with the book’s claims that she gave Valium to the singer when she was just 12, tried to pimp her out, and threw boiling tea on her.
Carey, nor her co-defendants, are yet to respond to the legal action.
