Yes, that's Kristen Stewart. She plays Bella, the lead. She was the little girl in Panic Room, remember? I have seen a few interviews with her and she's acts a little superior, imo. She's only 18, so I'm sure it's just immaturity, but she always comes across to me like she is above all this silly Twilight stuff. She is very pretty and good in the movie, tho.
I don't like her. She's too uppity for me. She was kind of rude to Robert P. on the Today show and I felt sorry for him. She was really boring with David Letterman.
