Court papers released Thursday in Britney Spears' custody dispute with Kevin Federline show she spends lavishly on clothes and entertainment, and doesn't save or invest any of her roughly $737,000 monthly income.

Spears' monthly expenses include $49,267 in mortgage for two houses, $16,000 for clothes and $102,000 on entertainment, gifts and vacation, according to her financial declaration.

Although she's often photographed eating fast food, Spears declares she spends about $4,758 per month dining out. Meanwhile, she spends zero on education, savings and investments and gives $500 a month in charitable contributions, the documents said.

She has to pay her ex-husband $15,000 per month in child support and $20,000 in spousal support. Spousal support will end November 15.

that's nice.
