9 Celebs in Serious Debt

Mariah Carey’s $38,000 veterinary bill inspired The Frisky to round up a few more celebs who owe lots of dough:

• Rihanna: By working out with a $1,500-a-day private trainer for a month, she racked up a nearly $30,000 bill—which her trainer said hasn't been paid.
• Jay-Z: Well, 22 flights on a private jet will cost you…$137,485, to be exact. The rap mogul is now being sued for the unpaid bill.

• Lindsay Lohan: The fact that she’s in debt comes as no surprise—but she was also behind on her rent, and apparently just two months got her $23,000 in the hole.
• Casey Johnson: The heiress had $75,000 in her bank account when she died, but she owed a rehab facility $74,750.
