Kevin Federline was livin' large last year.

The rapper, who just turned 30, shelled out more than $43,000 on Las Vegas hotels, food and shopping between May 2007 and January of this year, according to documents filed by his attorney in his ongoing custody battle with Britney Spears.

The papers were released by Los Angeles Superior Court on Thursday.

On the bill: $1,445 for clothing at Gianni Versace, $3,863 at TAO nightclub and $3,008 at the Hard Rock Beach Club.

Rest assured, Federline is a good tipper.

At Scores strip club, he gave $2,000 on a $365 meal bill.

Not all his money was for play, though.

He spent $74,102 in "music production" expenses to help his rap career, despite only earning $9,849 in "music income."

In March, a divorce attorney for Spears — who pays Federline's attorney's fees — argued that her client was being overbilled. A judge later ruled that Spears should pay $375,000 in his attorney fees.

Spears currently pays Federline $15,000 per month in child support for Sean Preston, 2, and Jayden James, 17 months. (See photos of Spears and her kids here.)

His rep recently denied reports that he and Spears took a Hawaiian vacation to repair their relationship.
