Both Paris and Nicky Hilton were hard partying all night as they appeared back on the club scene again; they had their own VIP booth while at the PURE nightclub at Caesars Palace in Las Vegas. It seems as if the siblings are getting back to their old ways of staying up all night and partying hard.

While Paris Hilton and Nicky Hilton we dancing to the beat other partygoers were going nuts, Paris was pleasing fans by taking time out to shake their hands, how big of her ah.

One thing that has changed with Paris was the fact that she was only drinking water and not alcohol.
