SIZZLER: Britney Puts K-Fed on an Allowance

Britney Spears has reportedly had it with Kevin Federline's "spend-happy" ways. So she's come up with a way to deal with it:

Insiders said Spears has put Federline...on a budget. "Each month, he will be allotted a certain amount of money for personal use - i.e., clothing, nightclubs, booze and day-to-day activities. Any big items - cars, or trips that go over allowance - need to be approved by Brit herself," said one source.

This isn't surprising, considering money problems are a big cause of stress in marriages, especially if the wife makes more money than the husband. But things should be fine once the royalties from "PopoZao" start rolling in.
