Gwyneth Paltrow has reportedly rubbed people up the wrong way on the set of Iron Man 2.
The actress has returned to the role of Pepper Potts in the sequel to the 2008 movie that was a huge box office success.
But she has made few friends on set and many of the cast wanted the character killed off or re-cast.
A source told Fox411: "Gwyneth is extremely cool at work. She's just a step above professional, too snobby."
"Gwyneth is not friendly to anyone, and tends to make people feel awkward and uncomfortable. She wasn't outright rude to Scarlett, she just didn't ever speak to her.
"Gwyneth went out of her way to avoid Scarlett, and they had zero contact, at Gwyneth's choosing."
Robert Downey Jr returns to the role of Tony Start and the movie is scheduled to be released in May 2010.
