The Hills Girls and Mariah Enjoy NYC Nightlife

Last night was a big one for the stars of MTV’s reality show “The Hills.” And after the premiere came an exclusive afterparty.

As Lauren Conrad left the Beatrice Inn following the premiere, she seemed annoyed with the paparazzi that were awaiting her exit. Still, she looked fabulous in her navy evening gown and prom-style updo.

LC’s pal Whitney Port also did what she could to avoid the shutterbugs as she left the scene of the party. But her multicolored dress underneath her trench coat minimized her ability to slip off into the night.

Audrina Patridge kept the party going all night long, heading to downtown New York City after things died down at the Beatrice. She wore a dark grey tweed jacket overtop her canary yellow dress and smiled as she mingled with bystanders.

And never one to miss out on the spotlight, Mariah Carey seemed thrilled to step out of her trailer to say hi in between the premiere and afterparty.
