Jennifer Aniston has been accused of diva-like behaviour on the set of her new movie.
A source told Radar Online that the 44-year-old star "acts better" than other people on the shoot.
The actress is currently filming the Untitled Elmore Leonard Project with Isla Fisher, Tim Robbins and Will Forte.
"Every day at lunch the entire cast and crew head to a cafeteria facility where they all sit down and eat lunch together for well over an hour," the insider told Radar.
"But the only person who doesn't eat with everyone else is Jen. She quickly grabs a lunch to go and leaves."
The insider claimed Aniston's trailer is situated much further away from the set than the rest of the cast and crew.
And the star's RV is apparently a much more fancy model than anybody else's.
"All the actors ride in normal production vans when they head to lunch, but Jen has her own luxury SUV," the source said.
"Not only is Jen's private trailer miles away from the set, but she heads all the way back there each day to eat her lunch away from everyone else," the insider added.
"It's just unnecessary. There's no reason why she has to act any better than anyone else on that movie set."
Although the former Friends star is not "outwardly rude" to her work colleagues, her behaviour indicates she is "not approachable," according to the source.
Aniston took a break from filming to attend the Oscars on Sunday where she presented an award.
