A new report says that Actress Charlize Theron is gobsmacked about the much maligned Stewart-Sanders affair. The “Snow White and the Huntsman” Actress is extremely sad and made about this untoward situation. In fact, Theron is said to be absolutely furious, especially given her tight relationship with all parties involved.

“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.”

The source adds, “When they were filming… Charlize felt like an older sister to Kristin, and they were always sharing advice.” But, it seems, Stewart didn’t share quite everything with Theron.

The 36-year-old South African beauty became so close with Stewart, 22, that she asked the ‘Twilight’ actress to be her adopted son Jackson's godmother, and now feels betrayed and confused about how to handle the situation.

The insider added, “Charlize confided to her new pal about her adoption plans. She even asked Kristen 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 Kristen 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 Kristen.”

Stewart was caught on camera locking lips with Sanders on July 17, but has branded the incident a ‘momentary indiscretion’ and issued a formal apology to her boyfriend of three years Robert Pattinson.
