The Sun is saying that singletons Reese Witherspoon and Jake Gyllenhaal have hooked up after working together on the movie Rendition. Of course, the thriller also stars Meryl Streep and Alan Arkin, who didn’t hook up – at least not with each other. As far as we know. (They both have Oscars so there’s nothing to be gained from the relationship.) But sources have been quoted as saying that the two young Hollywoodians, Jake and Reese, have been hanging together in New York. “She has been over to his house but she’s always very careful to make sure they aren’t photographed together.” Because then gossips might say they were hooked up.
