Jennifer Aniston is giving her former flame Vince Vaughn another chance after an impromptu meeting with the actor. Sources say Vaughn joined Aniston and a group of her friends for a night in Hollywood after spotting them at a hotel restaurant.

“She was obviously thrilled to see him. She giggled quietly at his jokes. She suddenly darted around the table, sat in his lap, and gave him a big kiss,” says on onlooker.

The witness claims the couple left together and Aniston was “smiling and waving.”

Another source says Vaughn and Aniston have rekindled their relationship but decided to keep it quiet. “Jen and Vince have quietly started seeing each other again, and she’s never been happier,” the source said.
