After four seasons of makeups and breakups, crying and gossip, “The Hills” had its big season finale Monday night in New York. A strange choice of location for such a Los Angeles-centric show, you might think. Not really. With Whitney’s spin-off show “The City” — the new hot show to watch (until season 5 of “The Hills,” of course) — set in New York, the landmark Tavern on the Green, all decked out in Christmas lights and ice sculptures, was the perfect holiday-themed location for the big bash.

The one major downside: It was bloody freezing!

But still, that didn’t stop all of the cast from turning up to hit the red carpet — and it certainly didn’t stop the girls from putting fashion first and hitting the carpet with short skirts on.

First came new sisters-in-law Stephanie and Holly. Maybe someone should have pointed out that they weren’t actually filming an episode of “The Hills” that evening. Within seconds of my live interview with them (and the question “Do you think the marriage will last?”), both girls squared up to each other and had a full-blown argument on live TV.

Frankie and Brody, who I think were both a bit tipsy, came next, followed by Justin. I didn’t really know what to expect from the infamous Justin Bobby. Anyone who watches the show will tell you that he comes across as a little bit of a … But on yesterday’s show he was actually smiling and, dare I say it, happy.

After Lo came Audrina. Nice girl! Let’s leave it at that.

And finally, the lovely Whitney and Lauren. Lauren looked great as always, bouncing between the Team Lauren clique in the VIP bar and her official “Hills” filming duties. Whitney’s outfit was a little unusual. But then again, with her new show set in New York, she is being called the “new Carrie Bradshaw,” so I guess it works.

Who am I forgetting to mention?

Oh, yeah! The true stars of the evening, Spencer and Heidi Pratt. They are undoubtedly the villains of the “Hills” cast; these two actually seem to revel in the hate. And yes, the drama on “The Hills” is real. Not only did they keep well away from Team Lauren, once the show was over they didn’t join the rest of the cast at the afterparty. Instead they headed back for a quiet night in at their hotel. I guess that’s what newlyweds do!
