Jennifer Aniston made a quick clothing change after the NYC premiere of The Bounty Hunter last night and headed back out on the town! Jen donned a short, sexy black dress with a leather jacket as she headed to Tao to meet up with co-star Gerard Butler for the official after party! “Jen was in an unusually good mood,” an onlooker told OK!.

Jen and Gerard sat next to each other at the banquette and talked to one another with their faces very close.

“Jen would often rest her hand on his chest and they talked,” the insider said. “They were surprisingly intimate moments, considering how many people were around them. Without a doubt, they are close.”

Gerard  definitely knows how to work a crowd!

“Gerard made himself the center of attention, standing on the seat and holding court in front of a huge group who were laughing along as he shook hands and playfully tensed and poked at his abs,” the onlooker told OK!.  “At times it looked more like a Gerard Butler concert than a party.”
