Scarlett Johansson & Gwyneth Paltrow ‘Come To Blow...

Scarlett Johansson & Gwyneth Paltrow have had a furious bust up on the set of their new movie Iron Man 2, according to a new report.

Running With Scissors star Paltrow — who is married to Coldplay rocker Chris Martin — is said to be furious that 24-year-old Johansson is hogging all the limelight, prompting fierce rivalry between the pair.

“Gwyneth has become very frustrated with Scarlett,” a source told British newspaper The Sun. “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.”

“Gwyneth and Scarlett have never been particularly close,” the insider added. “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 half way point.

“In fact, it’s quite the opposite.”

“The most spectacular sequence in the movie is a huge fight between Robert and Mickey Rourke, and she is going to be right in the thick of things.

“That section of the movie is going to be three straight weeks of filming in June.

“It is by far the most expensive sequence, the centerpiece of the whole project.

“Gwyneth’s break has come at a perfect time.

“She can recharge her batteries before returning for her chance to show who is boss.”
