CASH-SPLASHING MARIAH BLOWING HER DOUGH!

Drops 1M/month all she wants for Christmas is everything!

GREEDY Mariah Carey is burning through a staggering fortune — sources say she drops up to a million bucks a month on so much useless stuff she can’t even open all the packages!

“Mariah used to be more cautious with her money. She was always extravagant but there were at least some limits, but not anymore,” snitches an insider.

“Now it seems like she just lives her life to spend money. No price tag is too high — and the more expensive and exotic something is, the more she likes it!”

Materialistic Mariah — who is worth $340 million — rakes in a whopping $3 million a year just on her holiday hit All I Want for Christmas Is You, and sources say she treats it like mad money, squandering it as fast as she can on “obscenely expensive” designer duds and crates of champagne.
