Kristen Stewart parties with Garrett Hedlund

Kristen Stewart reportedly partied the night away with Garrett Hedlund.

Kristen was last spotted in Los Angeles on June 22 at the premiere of the film A Better Life with Taylor Lautner, and according to Hollywoodlife.com she hit up the film’s after party at The Ritz-Carlton with her On The Road costar Garrett.

Several eyewitnesses told HollywoodLife.com that Kristen 21, and Garrett, 26, looked happy to be spending time together. That said, there was no intimacy between the pair — just two great friends and costars having fun.

“Kristen and Garrett were both at the A Better Life afterparty, but Taylor was not there,” the source said. “It was interesting that Garrett arrived to the premiere late and by himself. Maybe he purposely didn’t want to be seen with Kristen to spread rumors, but they did hang out together later.”
