Reese Witherspoon and Jake GyllenhaalReese Witherspoon has reportedly demanded a ban on mobile phones on the set of her new film Rendition to stop camera-phone pictures being taken of her and co-star Jake Gyllenhaal.

After separating and filing from divorce from husband Ryan Phillippe last month, Reese is adamant about not being linked to Jake in case it affects the divorce proceedings.

A source told Us Weekly that “Reese doesn’t want any rumours about her and Jake” and that the movie’s makers, New Line Cinema, have agreed to the ban - but the studio has refused to comment on the matter itself.

Earlier pictures from the set showed Reese wearing a fake pregnancy belly and laughing with Jake.
