MARIAH CAREY DROPS $100K A MONTH FOR 90210 ZIP

Mariah Carey doesn't need a billionaire to live like one ... she's paying $100k for a place to call home.
She's leasing a 9 bedroom, 10 bath Bev Hills estate, complete with a pool, tennis court, theater, and 2-lane bowling alley.
The 15,000 square foot home retails for $23 mil.
So Emil Hartoonian, Mariah’s realtor, doesn't just sell big estates, he works with tenants too ... if they're rich enough to drop more than a mil a year in rent.
