Paris Hilton busted out her best pvc outfit last night for the grand opening of the Pussycat Dolls Lounge at the Viper Room in Los Angeles in a scene that looked like a regular country club social.

Paris was joined by the lounge's namesake, Nicole Scherzinger and the rest of the gang, who were also glad in shiny vinyl lingerie.  The Pussycat Dolls were pulling double duty as they performed at the American Music Awards. 

Tila Tequila and her main squeeze Courtenay Semel also showed up for the grand opening; apparently Courtenay's dominatrix wear was at the cleaners.
