HOT GALLERY: The Hills Girls Get Down to Business

Audrina Patridge and Kristin Cavallari looked very chummy as they filmed The Hills on Feb. 24 at the Diesel store on Melrose in West Hollywood. Seems like their days of fighting over Justin Bobby are over, especially now that Audrina has been dating Ryan Cabrera!

The reality stars were filmed doing what they do best — shopping!

Wonder what drama is in store for The Hills cast?
