Washington, Nov 2 (ANI): The release of Britney Spears and Kevin Federline's financial details as part of their ongoing court battle has revealed just how the singer spends the millions she's earned.

The new court documents have revealed some intimate details about the popstar and her ex-husband's income and expenses.

According to the documents, Federline bagged more than a half million dollars in 2006, primarily from entertainment and endorsement deals. The documents have revealed that he earned 3,300 dollars in royalties in 2006 for his debut song "Popozao."

However, excluding business expenses, he only grossed 7,436 dollars that year.

Spears' monthly income is approximately 737,000 dollars.

Like their incomes, the documents show how their spending habits also vary.

The 'Toxic' singer spends 102,000 dollars on entertainment, gifts and vacation, 49,267 dollars on mortgage payments, 16,000 dollars on clothes, 4,758 dollars on eating out and 2,500 dollars on phone bills.

Federline's expenses, on the other hand, include 5,000 dollars on entertainment, gifts and vacation, 7,500 dollars on rent, 2,000 dollars on clothes, 1,500 dollars on eating out and 750 dollars on phone bills.

Federline is entitled to receive 15,000 dollars a month in child support payments from Spears. (The amount may change, depending on how much more custodial time he ends up getting.)

He is entitled to get the payments until the couple's sons become adults, and since Spears earns more.
