VIDEO & PHOTOS: The Hills Cast Celebrates Big Finale In Hollywood

The Hills farewell party was held Tuesday at Hollywood's Hotel Roosevelt, and RadarOnline.com has all the scoop on the event as the show concluded its successful six-season run on MTV.

Most of the beautiful divas -- including Lauren Conrad, Audrina Patridge, Kristin Cavallari -- were front-and-center for the celebration, which marked the end of the popular series. Heidi Montag was not there, and Spencer Pratt wasn’t invited, though he tried to crash the party by wearing a lame old man disguise. ( It didn't work.)

The show's final scene is emerging as a real talker, as we see Cavallari in a car heading away from LaLa Land en route to a glamorous unnamed destination in Europe ... until the camera pans away to reveal crew members and cameramen on a Hollywood lot.

Hunky Brody Jenner told MTV following the shindig that the ambiguous ending was intended to make viewers think about if the show was truly reality TV — or scripted.

"The thing is, as you saw on the end -- what's real and what's fake, you don't know," he said. "Our relationship, the entire time could have been fake. That's one of the questions: what was real and what was fake, and we left it open."
