Mariah Carey and her billionaire fiance, James Packer, made headines when they recently broke up. The singer now wants the $50 million dollar prenup arragement. Initially, reports surfaced that she wanted compensation from him for the highly-publicized disagreement the couple had on a yacht in Greece. However, TMZ now reports that Carey wants Packer to pay her $50 million because that's what she would have walked away with if they already signed their prenup agreement.
