They were always only friends. He has repeatedly said they are just friends and she has to. They did have something on the Twilight set. Rob was very immature and got into his role. When the movie ended, he said it took him 2 months to get out of it. He is a loner and had never been so involved with a girl before and seeing someone for 5 months everyday like he did with Kristen confused him for a bit. Once he got to know the real Kristen, he was not interested. Kristen came out at sundance Film Fest and Runaways DVD. Once she lost him, she went a little crazy. That is why all the fighting, bad pr, finger salutes, hostile behavior, decline in her looks and appearance happened. She has recently been told to knock it off and act like a professional. She is looking and behaving better. Her reputation is in tatters from her unprofessional conduct during the past years. Before every premier, she does or says something stupid. At Eclipse, she was asked what advice she would give young girl fans. Kristen said "Be healthy and fxxx everyone". This girl should have been fired years ago for the bad pr she created. Rob and Taylor carried these Movies and had all the pressure. All she did was insult the fans, act and dress like a skank often and create bad pr. Her "we are, we aren't, I'm a lesbian" and "Rob could **** on the Queen's face and get away with it" comments were the final straw for most people.
