The male goldminer currently known as Fed-Ex is out of dough, that’s the word from celeb sources in California.

Rumor has it that Britney’s soon to be ex-husband is so hard up for cash that tried to return roughly $15,000 worth of expensive Japanese designers that Britney bought for him to a high-end Cali retailer. The LA fashion house wouldn’t give Kev any cash, but did supply him with store credit. Federline is trying to dig up ‘pocket money’ by selling the credit he received in exchange for the clothes. The sleazy “rapper” will be featured in an ad for next month’s SuperBowl.
