Cloverfield stars Jessica Lucas, Odette Yustman and Lizzy Caplan were all radiant at the Los Angeles premiere of the popular monster-attack flick. Intentionally cast as "unknown" actresses, they easily passed for leading ladies on the red carpet.

Also at the premiere, almost everyone from The Hills!

Audrina Patridge, Lauren Conrad, Heidi Montag and even Laguna Beach star, Kristin Cavallari were all there. We're a little shocked at how dressed up Kristin is. She dressed as if she was a star of the film. Our favorite is Lauren. The print of her dress is really fun and the zig zag hem of the dress makes it pretty unique. Although we've got to hand it to Heidi, she looks way better than she did here.

Also in attendance, Michelle Trachtenberg (remember Harriet the Spy?), Lindsay Lohan and Ashlee Simpson (with a new red-haired look).
