Paris Hilton and slutty sister Nicky partied up LAX in Las Vegas for an awesome New Year's Eve party. Paris said her resolutions for 2008 include eating well and working out. How cliche.

Meanwhile Paris was spotted cozying up to Britney Spears' ex-husband Kevin Federline.

The hotel heiress, who has become good friends with Britney after partying
with her several times this year, was seen laughing and joking with Kevin at
Las Vegas' LAX nightclub on Saturday.

A source said: "Kevin and Paris were having fun. He kept shouting out her
name and gave her a kiss on the cheek and then whispered something in her
ear. It looked as though they were getting quite friendly."

Britney was reportedly furious after seeing photographs of Paris and Kevin
together over the weekend.

This isn't the first time Britney has felt betrayed by one of her friends
recently.

Lindsay Lohan is said to have upset the 'Toxic' singer by dating Britney's
ex-lover music producer J.R. Rotem.

Although Kevin seemed to be enjoying himself with Paris, he was left
red-faced after deciding to grab a microphone and rap to the crowd.

A source told gossip website TMZ.com: "Kevin tried his best, but all he did
was spew a loud, heaping load of annoyance. Club goers were fleeing for the
exit once he started."

Meanwhile, Kevin's lawyer Mark Vincent Kaplan has revealed he is determined
to depose Britney in the New Year.

Kaplan said: "Britney Spears will have her deposition early this year. We've
got a lot to talk about. Kevin isn't interested, nor am I, in punishing her.

We just want to get information necessary to proceed further

Britney missed a scheduled deposition in December over the custody of the
couple's two children, Sean Preston and Jayden James, after claiming she was
ill.

Kaplan also said Kevin had a "happy" Christmas with Sean Preston and Jayden
James, his ex-lover Shar Jackson and their two children Kori and Kaleb.

Kaplan added to People magazine: "It was a good Christmas for all. They were
great. Kevin had all of his kids and it was a big, wonderful family setting.

He was really happy, and the kids were happy."
