Paris and Nicky Party in Vegas

The sparkly Hilton sisters were seen staying up all night, partying in a VIP booth at PURE nightclub at Caesars Palace in Las Vegas last night. It's just like old times!

The siblings are back in full effect on the club scene! Paris and Nicky literally hopped around to the beat, while partygoers went nuts -- with Paris even taking time to shake hands between shaking her moneymaker.

One noticeable change: Paris sipped water instead of the bubbly -- then handed the half full bottle to a fan. Paris knows that her fans need to stay hydrated!
