According to the legal docs obtained by OK, Kevin Federline has outrageous spending habits.

Kevin spent $50,489.71 over an eight-month period on hotel rooms and refreshments in Las Vegas.

In one day, K-Fed used his business card to spend $2,632.50 at TAO Beach (the pool club at the Venetian Hotel). On another night, he spent $2,862.60 at TAO nightclub. One day at the Hard Rock Beach Club cost him $3,008.33.

At Kevin's rockin' New Year's Eve at the Vegas branch of upscale strip club chain Scores, he racked up a $365 tab — and left a $2,000 tip!

Kevin Federline's lawyer Mark Vincent Kaplan tells OK!, "What Mr. Federline may have purchased for gifts for others, or entertaining and/or hosting parties is irrelevant, though obviously, and unfortunately, the other side tried to distract the court from what and how one should vacation."
