Us Weekly reported in December 2011 that this duo, who worked together in "Snow White and the Huntsman," become "inseparable" on set. And it wasn't memorizing their lines that brought them together. It was food! "They're both really reserved, but they've had a few dinners," the mag reported. "They're serious cooks and like to compare notes." Theron stirred the friendship pot even more by adding this about Stewart: "We met on a plane going to Comic-Con. You know when you meet someone and it's effortless? It was instantly amazing." How sweet!
