$1.25 Million is probably loose change to Mariah Carey, but we bet she still doesn’t want to hand it over in a lawsuit filed by none other than her sister…

According to reports, Mariah Carey is being sued by her older sister Alison Carey for some of the allegations she made against her in her autobiography, The Meaning of Mariah Carey, which was released last year.

Alison Carey alleges that the memoir caused her “emotional distress”, and is seeking damages for the “heartless, vicious, vindictive, despicable and totally unnecessary public humiliation” caused by her book.

Alison Carey is representing herself in the lawsuit against her world-famous sister, and added that she is now “severely depressed and uncharacteristically tearful since the publication of defendant’s book and now struggles, after a long time clean, with alcohol abuse”.

For anyone who hasn’t read the memoir, the 50-year-old pop diva wrote that her 59-year-old sister had drugged Mariah with Valium when she was just 12 years old, and allegedly also offered her cocaine.

Mimi also alleged that her sister caused her third-degree burns when she threw a cup of boiling tea over her back.

Mariah Carey also wrote that Alison would allegedly “barter her body for money or drugs”, and even recalled a time when she was left alone with her sister’s boyfriend when she was just 12 years old, who then allegedly forced himself on her.

“Big sisters are supposed to protect you – not pimp you out,” Mariah wrote.

According to the lawsuit, Alison claims that the autobiography is full of “cruel and outrageous allegations”, and that Mariah “used her status as a public figure to attack her penniless sister, generating sensational headlines describing her lurid claims to promote sales of her book”.

Mariah Carey has yet to respond to the lawsuit – which was filed at the New York Supreme Court earlier this week – but we don’t think she will take this lying down.
