Britney Spears isn't in charge of her finances, but that hasn't stopped her from accumulating a fortune.

According to new docs filed in her conservatorship case, and obtained by TMZ, Brit has reported assets totaling more than $32 million since December 31st, 2010. She needs the cash, too, because her bills are huge.

Here are some of her expenses from 2010 alone:

  • Child support and care: $303,673.72
  • Cleaning expenses: $27,265
  • Personal grooming and wardrobe: $61,295.12
  • Automobile expenses: $59,351.92 (and she didn't even buy a car that year)
  • Rent for Calabasas house: $19,000 a month
  • Electric bill: $5629.43 in just one month
  • Gas bill: $1841 in just one month
  • Water bill: $2278.27 in just one month
