Scarlett Johansson has reportedly upset her Iron Man 2 costar Gwyneth Paltrow. While the Match Point cutie is in Madrid for her job as the new face of Mango, the ‘ Shakespeare in Love’ star is fuming with the fact she doesn’t appear on the superhero ads. "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 says.
