Both Lauren Conrad and frienemy Heidi Montag showed up at the Us Weekly Hot Hollywood Party at Opera in LA on Wednesday night. Although event planners made sure to stagger their red carpet arrivals so that LC was long done with the red carpet by the time Heidi arrived.
So, the real question is…..
Which Hills co-star looked better, Lauren or Heidi?
YOU decide!
