Mariah Carey is demanding $50million compensation from her ex-billionaire fiance

He didn't even marry her but Mariah thinks she deserves $50million for the time she spent with ex, James Packer....lol. Read the report Mariah Carey has privately made a demand to James Packer ... he needs to pay her $50 mil ... or else. Sources connected to the now warring ex-couple tell TMZ ... Mariah believes James has cost her tens of millions of dollars, and here's why: -- She claims he got her to move from New York to L.A., uprooting her entire life, so he could be near his kids. -- She claims the incident on the yacht in Greece -- where she says he did something awful to her assistant -- has traumatized Mariah so much she had to cancel the South American leg of her tour. -- He made various financial promises to her. No comment from Packer.
