Fashion Faceoff! 'Drina, K-Cav And Steph Battle For Best Dressed

As the reigning smog capital of the world, L.A's pretty much the last place you'd wanna go to bone up on your astronomy. 'Course, if it's stargazing you're after, you won't find a better view on this side of the equator -- and last night, all the biggest/brightest stars of Tinseltown were out at Us Weekly's annual Hot Hollywood party.

So who lit up the room? Amid the usual melange of musicians, socialites and actresses (like Leona Lewis, Nicky Hilton and Eliza Dushku), Hillzies Kristin Cavallari, Audrina Patridge and Stephanie Pratt glimmered and shined in glitzy metallics, sparkly bangles and sexy corsets. Take a look at our Hills gals' shimmery red carpet style and let us know who you think had the most dazzling dress of the night!
