Mariah Carey is being sued for at least $1.25 million by her estranged sister Alison Carey.
Alison is claiming she suffered emotional distress over the abuse claims in Mariah's new book, "The Meaning of Mariah."
The book claims that Alison gave Mariah Valium, tried to pimp her out and threw a cup of boiling tea on her causing third-degree burns when she was 12.
Alison is disputing these allegations and claiming that Mariah has no evidence or proof to support what the book claims.
