Joan Jett has heaped praise on Kristen Stewart saying that she did a great job in her new movie The Runaways.
Stewart takes on the role of Jett in the biopic picture that charts the rise of the all girl rock band.
In an interview with U.S. Weekly she said: "I think Kristen - well, both of them really - did an amazing job.
"When we first met, I talked and talked and talked at her for hours. About The Runaways, and told her stories I'd never told anyone else. I thought it was important.
"I gave her tape of me talking at 14 so she could hear the way I was."
"I wanted her to know Joan and not Joan Jett. You get so used to the hair and the makeup and the leather jacket as opposed to the person behind that and I wanted her to know the person. I think we really did get down to that."
Dakota Fanning stars alongside Stewart as Cherie Currie, the movie is based on Currie's book Neon Angel.
