If Kristen Stewart can cheat on him with her director, Robert Pattinson can certainly crash on the couch of one of his former co-stars! According to People, Pattinson is currently staying at Reese Witherspoon’s estate in Ojai, California as he deals with the fallout from Stewart’s adulterous revelation. After finding out Stewart was photographed kissing her Snow White and the Huntsman director Rupert Sanders, Pattinson decided to leave the house they shared together. He immediately turned to Witherspoon, his Water for Elephants costar. A source close to the 26-year-old Twilight star said he had his “heart ripped out.” Stewart is apparently equally as devastated. "Telling Robert was the worst thing she's ever had to do," the insider said. She’s reportedly turned to her Panic Room co-star Jodie Foster for support.
