Hot Shots: Stephanie Pratt and Lo Bosworth Go On A Panty Raid!

While you were cryin' your eyes out at Grey's Anatomy last night, Hills stars Stephanie Pratt and Lo Bosworth were giggling up a storm at the Undrest Pop Shop opening in L.A (or, the "undrest undie party," as Lo nicknamed it on Twitter).

Hangin' out together for the second straight night, (Wednesday was all about Maxim and micro-minis!), Lophanie surveyed the sexy underthings then got all Agent Provocateur in lacy black gloves and silky blindfolds. Check out these pix of the ladies scopin' out lingerie, then stick around and admire their pre-panty party poses, after the jump.
