Charlize Theron has only said kind things about her Snow White and the Huntsman co-star, Kristen Stewart. Charlize and Kristen became legitimate friends on the set of the movie which is why things are so awkward for Charlize – she's friends with Rupert's wife Liberty Ross and Kristen.
An insider said:
“Charlize is absolutely fuming with Kristen for having an affair with Rupert. She is very tight with Liberty, has often socialized with the family over dinner and cannot believe Kristen has done this."
The Oscar-winning actress reportedly "has great sympathy for Liberty and the kids."
