Mariah Carey is in her element around the holidays, but things may not be sunny behind the scenes. According to a new story, the 54-year-old diva is spending too freely, and friends worry she may spend her vast fortune. Celebrity Net Worth estimates Carey's wealth at $350 million—astronomical! The National Enquirer reported via RadarOnline that the Queen of Christmas spends over $1 million monthly and barely knows what she's buying.  An insider says, “Mariah used to be more cautious with her money. She was always expensive but had limitations, but not anymore. She appears to live to spend money now.” According to the insider, she spends money on champagne and “obscenely expensive” apparel. They continued, “No price tag is too high — and the more expensive and exotic something is, the more she likes it.” Carey also “loves to spoil everyone in her life at Christmas and orders gifts all year long to stockpile.” This is so ridiculous that the "All I Want for Christmas Is You" singer "has multiple rooms full of gifts."
