Kristen Stewart and Dakota Fanning are doing the press rounds for their film ‘The Runaways,’ and while they tried to portray the relationship between Joan Jett and Cherie Currie accurately, there were some limitations on filming those scenes for the movie.

“[Dakota] was 15, and I wasn’t allowed to grope her,” Kristen, 19, told Access Hollywood on Wednesday at the press junket for her new rocker film. “I’m actually not kidding, there are major restrictions that I don’t remember [from] when I was younger.

“I don’t want to give anything way. It’s a really passionate, hardcore scene,” she continued. “No, it’s just a kiss. It’s not really a big deal.”

Kristen and Dakota also said they both loved their wardrobes. I bet it was fun to dress up in those 70’s clothes!

Kristen confessed to Jay Leno that although she and Joan had some similarities, it wasn’t too helpful to her acting.

“You always feel the pressure [of portraying a living person accurately],” says Stewart. “It’s, like, if I don’t get every little thing right I’m going to kill myself. And we have very different tics. We’re both, like, ridden with tics, but they’re a completely different set of them.”

There’s a clip of Kristen’s interview after the break:
