Kristen Stewart arrived at LAX on Saturday evening after flying in from NYC. She was back in her hometown right in the middle of a big weekend for many of her costars. Her On the Road costars Garrett Hedlund and Kirsten Dunst have been making the party rounds this weekend. They hit Friday night's W magazine Golden Globes party, and Kirsten was solo for Saturday's Art of Elysium Heaven gala. Their project isn't in contention at this year's Golden Globes, but Kristen may attend anyway — her boyfriend Robert Pattinson is one of the many presenters at this year's show!
