Nicky Hilton parties it up

Nicky Hilton has always been the more reserved of the Hilton sisters. But it looks like darling Nicky has been taking some cues from her older and more scandalous sister, Paris.

Friday night Nicky celebrated the launch of her new jewelry line at Pure nightclub in Las Vegas and partied like only a hotel heiress could.

The 22-year-old sported Paris-like hair extensions, drank red bull and shook her booty in much the same way her big sister did at Pure just one month ago.

While Nicky appears to be living up to the Hilton party girl reputation, here's hoping her new turn doesn't include amateur videos or Rod Stewart covers.
