Kevin Federline reportedly turned down Paris Hilton’s advances when they partied together over the holiday period.

The pair were snapped enjoying each other’s company during a bash at Pure nightclub in Las Vegas on December 30.

However, according to insiders, Brit’s playboy ex-husband gave the heiress the big brush-off when she made her move on him.

“Paris whispered some pretty sweet and enticing words in Kevin's ear,” a Federline family insider tells PageSix.

“She basically asked him where he was staying and if he wanted to visit her in her own suite.”

According to their source, the Fedster passed on the offer but admitted, “It will not be so easy to deny her next time.”

Still, Paris hasn’t been short of male attention lately – as our gallery of her recent very public conquests shows.
