The former Friends beauty has been concentrating on her acting career since her split from Brad Pitt earlier this year (05) - but pictures publishing in British newspapers show the co-stars touching each other in a way which suggests they are more than friends.
In one snap published in the DAILY EXPRESS Vaughn has both of his arms wrapped around Aniston, while she has both of her hands resting on his thigh.
A movie insider tells the Daily Express, "They looked to be really enjoying each other's company. They were laughing and smiling and were very tactile together. There was definitely some chemistry between them."
