The blonde actress reportedly insisted on being driven 100 yards across the Los Angeles set on the first day of filming, on "He's Just Not That Into You," while co-star Drew Barrymore walked the distance.
Johansson, 22, also alledgedly demanded three assistants shielded her from the elements with umbrellas.
An on-set source said: "Scarlett's a total diva. Some people are cool, and others are not."
However, a member of the production team defended the "Lost In Translation" star's actions, saying: "We prefer talent use vans when filming on public streets, and Scarlett has only been professional."
Johansson splashed out $800,000 this summer on a "gigantic" new home.
She purchased the seven-bedroom Los Angeles property, located in the exclusive Hollywood Hills area, from film director Harold Becker.
