Kristen Stewart dishes on kissing Dakota Fanning

“It’s just something that we did.”is what Kristen Stewart says about filming her kissing scene with co-star Dakota Fanning in ‘The Runaways’. “In this story, it’s so not like a romantic thing. It’s just something that they just do.”

While opening up at Sundance on the much anticipated film, she added:“We had so many other really crazy things that we were intimidated by, like, we had a performance that day. So when that came up on the schedule we were like, ‘Whoa!’ But then, ‘Alright, whatever.’ It was sort of just like another thing.”

The hardest part for Stewart?Having to play guitar for Joan Jett.Kristen half-joked that it was “Horrible!” “At first, she was like, ‘Come on!’ She was actually kind of getting upset with me. She was like, ‘Ya gotta relax.’I kept telling her, ‘I can’t do it until we shoot it. Like I literally can’t.'”
