Mariah Carey's estranged brother is continuing to wage a legal war against the pop superstar, claiming she employed a fan who created a ruthless YouTube video about him, RadarOnline.com can reveal.
Morgan Carey claimed in a new legal filing that one of Mariah's Lambs, as her fans are known, made defamatory statements about him while rehashing shocking claims the Emotions singer made about her sibling in her 2020 memoir.
New Legal Battle
Mariah's brother claims a fan under the singer's 'control' made the allegedly defamatory video.
Morgan filed an amended lawsuit in March after becoming aware of the YouTube video created by a fan called Lambily, titled Morgan Carey: A Deep Dive Into Mariah Carey's Disturbing Older Brother.
He initially sued Mariah in 2021, accusing her of defaming him in her memoir The Meaning of Mariah Carey, where the superstar accused him of being violent.
A judge previously dismissed 14 of the 16 claims made in his original suit, and his appeal was denied in 2023.
The new complaint claims that "...the individual identified as responsible for this video, one Lambily, is within the employment and control of Mariah, and the statements in it were made by her both personally through Lambily."
Rehashing Old Drama
Mariah accused her brother of being violent in her 2020 memoir.
The video rehashed Mariah's memoir claims that Morgan was physically violent towards their mom, Patricia Carey. Her husband and the siblings' father, Alfred Roy Carey, abandoned his family in 1973, but not without plenty of drama first.
The documentary opened with Mariah reading a passage from the audiobook of her memoir about an incident involving Morgan and Alfred.
"It took 12 cops to pull my brother and father apart, and yet my mother trusted him the most. He'd become her strong man, her protector. Almost a father figure to her, a position that should never be filled by a son," the Long Island native stated.
The documentary featured Morgan bashing his sister.
The piece also included clips of Morgan bashing his sister, where he was shown saying, "Mariah is someone who holds grudges and is not empathetic, is not compassionate, and sees the world only through the filter of her own ego, and it's tragic."
In another clip, Morgan sneered, "The ego is so out of control that she feels like the rules of physics don't apply to her because she's Mariah Carey."
