Johansson, Paltrow spar on 'Iron Man' set

Scarlett Johansson and Gwyneth Paltrow have not bonded with one another during the filming of upcoming action sequel Iron Man 2, it has been claimed.

According to The Sun, ill feelings between the pair have resulted in tension on the set of the movie.

A source told the newspaper: "Gwyneth has become very frustrated with Scarlett. They come from different worlds and have completely different styles.

"Gwyneth has found Scarlett very demanding of the attention of the crew. It's not a happy set."

They added: "Gwyneth and Scarlett have never been particularly close. Gwyneth was looking forward to working with Emily Blunt, who was originally in line for the part, but it ended up being Scarlett.

"Gwyneth's had to live with that and she has been very professional, but she and Scarlett haven't developed a friendship on the shoot, which is almost at the halfway point. In fact, it's quite the opposite."

Johansson recently rejected news reports that she was following Paltrow's diet plans to lose weight for her role.
