Tama0026 on Twitter did some research, blew up some photos, and has come to the conclusion that it is Kristen Stewart’s arm in the photo that we posted earlier today. Check out her side-by-side comparison below.
EDITED: Confirmed direct from Summit entertainment that it is Kristen’s arm!
As for the bruises, we’re thinking they are probably higher up on her arms. With Stephenie as producer there is no way they are not going to be there.
