Robert Pattinson wants to know what really happened with Kristen Stewart and her backseat lover boy, Radar Online reports. "Rob wants to have a man to man chat with Rupert [Sanders] to find out exactly what happened between him and Kristen," says a source close to Pattinson. Because Kristen has already betrayed him with Sanders, her director on Snow White and the Huntsman, Pattinson "can't be sure that she will tell him exactly what went on between her and Rupert."
The source adds (somewhat illogically?) that Sanders "has a wife and a family to save, so Rob feels like he has nothing left to lose and would be honest with him." As for Pattinson, he was "blindsided" and is "going through the typical stages of being cheated on" (ie, heartbreak, anger, and now just wanting the facts). "And he'll do whatever it takes to find out the truth."
