Jennifer Aniston is not making friends on the set of her new film. According to sources, Jen has been mostly keeping to herself on the movie’s Connecticut set, eating lunch alone in her trailer, which is parked far away from fellow castmembers. A source says she is “the only person who doesn’t eat with everyone,” and that she “quickly grabs a lunch to go and leaves.” The yet-to-be-titled film also stars Isla Fisher, Tim Robbins and Will Forte. Insiders say Jen isn’t rude to anyone, but she isn’t exactly friendly either. “Her behavior is a clear indicator to everyone that she’s not approachable,” said the source. “And it’s just unnecessary. There’s no reason why she has to act any better than anyone else on the movie set.” A rep for the actress denies the accusation, stating, “Jennifer is having the most amazing experience working on this film,” adding that sometimes “she eats quickly and then heads to her trailer because she is learning lines or rehearsing with the other actors.”
