Nikki Reed, Emma Roberts celebrate young Hollywood with Teen Vogue

Pretty young things from all over entertainment congregated in Los Angeles on Friday night to toast (with sparkling cider, of course) Teen Vogue's Young Hollywood bash.

Emma Roberts, Nikki Reed, Kelly Osbourne, Raven-Symone and more turned up for the party at the Paramount Studios lot, featuring a fashion show from Michael by Michael Kors. Stylish brit Alexa Chung played DJ before band Fitz and the Tantrums took the stage, where model Agyness Deyn rocked out with folks such as Zelda Williams (Robin's daughter) and Kate Mara.

A tres Hollywood treat came from celeb and fashion photog Douglas Friedman, who created a custom photo booth modeled after a soundstage -- complete with a lighting grid and fog and wind machines.
