Jennifer Aniston and Vince Vaughn acted out their share of cozy moments while shooting The Break Up in Chicago this summer. Back in the city on Oct. 12, they were ready for another one. The duo sipped cocktails with another couple on the terrace bar at NoMI, a swank restaurant with breathtaking views of the Windy City.
Then they pulled a move straight out of the romantic comedy playbook: With temperatures dropping into the 50s, Aniston and Vaughn asked staffers for a blanket to ward off the chill and contentedly snuggled under the covers together. "She was all wrapped up," says an onlooker dryly, "with that guy she's supposedly not dating."
