Jennifer Aniston’s antics with Hollywood heartthrob Vince Vaughn are reigniting rumours of a romance between the pair. First the former Friends beauty is said to have spent the evening at the Four Seasons hotel in Chicago, where her The Break Up co-star Vince is staying. Then they were photographed hugging and kissing in a Chicago park during a break in filming. Jennifer (36) and Vince (35) recently denied any romantic link. But an onlooker says, “They seemed very comfortable in each other’s company and were quite spontaneous when they hugged”.
