Jennifer Aniston is rubbing co-workers the wrong way on the set of her new movie The Baster–about an unmarried woman who decides to conceive using a turkey baster.

The 40-year-old actress amazed cast and crew on the film’s New York City set after she refused to start shooting the movie because she was unhappy with her hair. Jen requested additional time to get ready during her first day on set.

A source tell OK! Magazine: “In the morning everyone had to wait to start filming because Jennifer asked for extra time to finishing blow-drying her hair.”

The former Friends star is also being criticized for her refusal to socialize with the other workers. While most members of the cast eat together, insiders say Jennifer stays to herself and eats alone.

“Jennifer refused to walk even a step outside the restaurant during the break for lunch. She had her car pull up right next to the restaurant so she could be driven less than a block to her trailer to avoid photographers.”

“Jennifer kept mostly to herself. She didn’t talk to anyone during the breaks.”
