Kristen Stewart has been banned from attending the New York City premiere of Robert Pattinson‘s new movie, Cosmopolis on August 13. If she tries to show up, security will be called. A source told RadarOnline: “Despite the fact Robert and Kristen have been communicating by cell phone, she will not be at the Cosmopolis New York premiere. Security was briefed and they were told that Kristen is not allowed anywhere near the red carpet or the after party. The decision was made because Robert just doesn’t want to see her. There were fears that she could use it as a chance to talk to him in person and that sort of drama is not wanted at the premiere. There’s also the fact that if she did attend, it would distract from the film premiere itself and the movie bosses are not interested in that sort of publicity.”Until then, Pattinson is laying low at Reese Witherspoon’s Ojai ranch. A source told the gossip website she related to what he was going through, saying, “Reese went through a very public cheating scandal herself when Ryan Phillippe went outside their marriage and hooked up with Abbie Cornish, so her first thought when she heard about Kristen and Rob was to reach out to him and make sure he was okay. Reese knows what it’s like to be on display when your heart is broken, so she felt like opening up her home to Rob was the right thing to do.”
