All summer long Jennifer Aniston and Vince Vaughn have worked side by side in Chicago, shooting scenes of warm intimacy for their upcoming romantic comedy The Break-Up. And so it was a familiar sight when the two were spotted together – her head resting on his shoulder, his arm draped across the back of her neck – in the wee hours of Aug. 15 at her hotel.
Except that this time, there were no cameras, no extras, just a tired duo sharing a quiet moment. "They looked very cozy and familiar," an observer says of the pair, who were joined by Aniston's bodyguard as they strolled to the elevators.
