"The Hills" seems like it happened a million years ago, even though it's final season was actually just last year. Reality TV moves fast. But for anyone looking for a reunion of sorts, they needed only be in attendance at the L.A. premiere of "Immortals" the other night, where two of the show's stars— Audrina Patridge and Kristin Cavallari— posed together for photos on the red carpet. They were all smiles and both looked great. They reminded us of another era in reality television. The golden age, if you will. They sure don't make those shows like they used to.
