London, May 19 (ANI): Gwyneth Paltrow is said to be furious with her ‘Iron Man 2′ co-star Scarlett Johansson for hogging the limelight on the sets of ‘Iron Man 2′.

Paltrow, 36, is once again playing the part of Pepper Potts, assistant to comic book hero Tony Stark, played by Robert Downey Jnr, in the second sequel.

“Gwyneth has become very frustrated with Scarlett,” the Sun quoted a source as saying.

“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.

“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 source added.

Johansson, 24, has been given the role of Natasha Romanoff, a sexy former spy known as the Black Widow. (ANI)
