The Hills Girls Compete on Red Carpet!

Hills stars Stephanie Pratt, Lauren Conrad, Lauren Bosworth, Audrina Patridge and Whitney Port all sparkled on the red carpet for the opening of the 26th Annual William S. Paley Television festival in Hollywood last night.

The girls were battling it out for the best dressed, especially The Hills' lead Lauren and The City's Whitney Port. Both let their hair down with loose, beach-ready tresses, and whereas Lauren opted for a sunny belted 3.1 Phillip Lim mini paired with brown strappy sandals, Whitney chose a white maxi dress and boho bangles.

We really love Audrina's side-bun hairdo! Which starlet do you think looks best?
