David Archuleta, Jesse McCartney, Charice, and Wilson Phillips performed and the grand finale tree lighting was accompanied by fireworks and fake snowfall.

The biggest star was not on stage but sitting in the audience, front row, and it was Arnold Schwarzenegger. I spotted him at the end of the festivities and right before the fireworks went off.  As soon as the celebration was over, Arnold was rushed right past where I was standing. Good thing the camera was ready!
