Washington, Feb 14 : Gwyneth Paltrow just does not know how her role will be in Iron Man sequel, for movie bosses are not revealing any details about the project.

The actress, married to rocker Chris Brown, played Tony Stark''s faithful assistant and love interest Pepper Potts in the 2008 comic book blockbuster, opposite Robert Downey Jr.

Although Paltrow will reprise her role in the sequel, she has no idea about the proposed plot for the new movie, as studio executives are keeping it all under wraps.

"They haven't even given me a script yet. They don't tell me anything," Contactmusic quoted her as saying.

She added: "I could be, like, a costume assistant in it. I know nothing. (Director) Jon Favreau said it would be good, so I believe him." (ANI)
