Britney Spears's lawyer argued in L.A. court that ex Kevin Federline should pay his own legal fees.

The court had previously ruled that Spears, 27, has to pay Federline's counsel Mark Vincent Kaplan "reasonable" attorney's fees.

Stacy Phillips told a Los Angeles court commissioner that the singer currently pays Kaplan $500,000 when he is only entitled to $150,000 to $175,000, PEOPLE reports.

Phillips mentioned how the rapper once tipped $2,000 on a $365 bill while out dining.

"If he is willing to tip someone $2,000, then he should be willing to pay the lawyer bills," Phillips said. "Mr. Federline needs to take responsibility for the very diligent work they do on his behalf."

Kaplan, argued that he is worth the price.
