Reese Witherspoon, wearing a prosthetic pregnant stomach, films a scene for her new film 'Rendition,' which is about a CIA analyst in Cairo who witnesses an unorthodox interrogation (torture?) of a foreign national by the Egyptian secret police. The film also stars Jake Gyllenhaal, Alan Arkin, and Peter Sarsgaard. Since filming has started, rumors have swirled that Jake and Reese were more than just co-stars. It has been reported that Reese, who recently split from hubby Ryan Phillippe, has banned cell phones from the set to keep any sneaky snaps of her and Jake filming together, preventing any more rumors.
