SPOTTED: Lily Collins and her Mortal Instruments: City of Bones co-stars Jamie Campbell Bower, Kevin Zegers, and Robert Sheehan at a meet & greet for the film held at The Americana at Brand Tuesday in Glendale, Calif. Also on hand were director Harald Zwart and author Cassandra Clare.

The 24-year-old actress simply shimmered wearing a shiny top and skirt by Bec & Bridge. She completed her look with Christian Louboutin shoes and a Pomellato necklace.

Fans lined up for hours just to get a glimpse of the stars. The cast said they first got a sense for their insane stardom at Comic Con. Lily said about the buzz: “Oh it’s been crazy. We had one girl faint for Jamie.” She added, “It’s been quite mental. We’ve had babies named after Jace, we’ve had real rune tattoos and it’s people that are buying the tickets. That’s like the best interaction that you can have.”
