Actress Gwyneth Paltrow, who returns as Iron Man`s PA Pepper Potts in `Ironman2` is furious after she was left out in the movie posters which featured her new co-star Scarlett Johansson prominently.

The Oscar-winning actress is afraid that Johansson, who plays a Russian spy, will overshadow her role in the movie.

The `Matchpoint` beauty appears in a promotional campaign alongside the film`s other stars, Robert Downey Jr and Mickey Rourke while Paltrow remains missing.

And now Paltrow has been left out in the promotional press as well, Daily Mail reported.

"Gwyneth was afraid she`d be upstaged by Scarlett and not being in the campaign was the final straw. She is furious she`s been left out," a source said.

Paltrow, 36, now reportedly plans to boycott a promotion in San Diego later this month.

"She`s heading to New York instead, she`s so angry," added the source.

However, a spokesman for Paltrow denied reports saying, "She was not at all upset. The fans will get to see more of Pepper Potts as we get closer to the film`s release next May."
