Paris Hilton, Lauren Conrad, songstress Katy Perry and "Dollhouse" star Eliza Dushku Nylon magazine celebrate the launch of its TV issue.

The bash, held at the Hollywood Roosevelt Hotel's Tropicana Bar was also attended by "90210" stars Shenae Grimes, AnnaLynne McCord and Jessica Stroup, who are featured on the cover of the issue, and were joined by their co-stars Ryan Eggold, Dustin Milligan and Michael Steger.

The party goers were treated to specialty cocktails by Effen Vodka and Venom Energy Drink -- and, of course, copies of Nylon!
