Kevin Federline and Paris Hilton were spotted in Las Vegas on Sunday together at LAX, according to People magazine. Federline was at a VIP table with his parents, brother and friends when Paris arrived. She visited the DJ booth and then wandered over to Federline’s table, where they shared tequila shots before hitting the dance floor. A source close to Federline snitched to the mag that the two went to Hilton’s room together after leaving the club. They were in Sin City to host separate New Year’s Eve parties—Paris at LAX, Fed-Ex at Tangerine.
