Mariah Carey I'm One Of The Poorest People In The Room

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: James Packer $4.6 bil, Kerry Stokes $1.26 bil, and top dog Ron Perelman $14.7 bil.

At least Mariah wasn’t at the bottom of the financially stacked list ... her pal, Brett Ratner was also there and he’s only worth $65 mil … he’ll only have to worry about leaving the tip.
