Charlize Theron Furious With Co-Star Kristen Stewart Over Affair With Married Director

By Jon Boon - RadarOnline.com Reporter

Charlize Theron has blown a gasket over Kristen Stewart’s scandalous affair with married movie director Rupert Sanders, RadarOnline.com is exclusively reporting.

The South African-born beauty, who struck up a friendship with K-Stew during filming of Snow White and the Huntsman, is also close pals with Liberty Ross, the wife of Sanders!

And Kristin’s actions have left Charlize, 36, in a difficult position. 

“Charlize is absolutely fuming with Kristen for having an affair with Rupert,” an insider revealed.

“She is very tight with Liberty, has often socialized with the family over dinner and cannot believe Kristin has done this.

“When they were filming Snow White and the Huntsman, Charlize felt like an older sister to Kristin, and they were always sharing advice.

“Charlize confided to her new pal about her adoption plans. She even asked Kristin if she wanted to be her baby Jackson’s godmother – that was how close they were.

“But Charlize had no idea what was going on between Rupert and Kristin and now feels completely betrayed by the whole incident.

“It’s certainly left Charlize between a rock and a hard place, because she feels great sympathy for Liberty and the kids and yet, she has a sisterly love for Kristin.

As Radaronline.com previously reported, Stewart issued a public apology to boyfriend Robert Pattinson on Wednesday where she called the illicit affair a "momentary indiscretion."

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry," Stewart said in a statement.

The damage control comments come in light of a published report that claims the Twilight Saga star and the 41-year-old filmmaker could hardly keep their hands off one another as they traveled around Los Angeles together on July 17, and a series of photos confirms the affair, showing them in a number of steamy clinches.

“He was all over her,” said one photographer who witnessed the hi-jinks, while another said Kristen “would only take a break from kissing when they thought someone was walking by.

“It seemed like they couldn't get enough.”
