Mariah Carey is used to being the top diva at the table but after a power lunch with a bunch of billionaires she had to take a back seat … financially. Mariah finally got off the yacht and grabbed a bite with her new Australian beau, James Packer, and a few of his billionaire mates. Yeah Mariah is worth $500 mil but that’s pennies compared to her dinner company. Packer himself is worth $4.6 billion, while Kerry Stokes is worth $1.26 billion and top dog Ron Perelman is worth $14.7 billion. At least Mariah wasn’t at the bottom of the financially stacked list as her pal, Brett Ratner was also there and he’s only worth $65 million.
