Robert Pattinson and Kristen Stewart were trying to hide their faces so could not be recognized while smoking. This may be some relaxing time for the duo yet they were not comfortable. When they dig in smoking, a hat came for Kristen Stewart which shows that she does not like to be seen in public smoking. Kristen Stewart regulates her image, so when smoking occurs, she tries to hide herself.
The same was for boyfriend Robert Pattinson who had a hat and hoodie when started smoking and remained quite unidentified.
Is this sound so pathetic!!
