Lauren Conrad and Lo Bosworth Share Tense Lunch

Filming is underway for the new season of The Hills.

The show's leading lady, Lauren Conrad, and her BFF Lo Bosworth were seen shooting over lunch at Mira Le in West Hollywood today.

Neither of the two co-stars showed many smiles though as the conversation seemed to grow more and more tense as the lunch went along.
