24-year old Pattinson explained: "Kristen is always really good but also clearly speaks her mind. That can be a bit uncomfortable."
He continued: "After we shoot a scene she sometimes looks at the director and says, 'Let's do that again.' If I did that she would probably kill me! She would probably say something like, 'Shut up! The scene was perfect!' "
Meanwhile R-Pattz, who is currently shooting new movie Water For Elephants also claimed that stories written about him are often false - because he rarely ventures outside.
