This in from MTV News cameraman and producer Todd Brown, who spent last night at the party for finale of the third season of “The Hills”:

The party was held at a multi-million dollar mansion high up in Beverly Hills, far above Los Angeles. In order to get to the top of the hill, we had to load in to vans and drive up a steep and windy mountain road. Most of the “Hills” cast were there — as well as Usher, The All-American Rejects, Tyga, Jessie McCartney, and Schwayze, to name a few. Surprisingly, and probably because of some underplayed and hardly-ever-mentioned beef with Lauren Conrad, Heidi Montag and Spencer Pratt did not show.

In addition to the stars, there were hundreds of cocktail dress-wearing young fans, there for the chance to see their favorite semi-reality stars up close. After walking the red carpet, the “Hills” cast mingled with the fans and took pictures — and then they all watched the show together on a huge, 30-foot outdoor screen.

The entire event was shot with more than 7 different camera crews, including the Goodyear blimp(!), and aired live on MTV and MTV.com.
