When she’s not being Bella in the Twilight movie series, actress Kristen Stewart is being Joan Jett in her new movie, The Runaways. The new movie is about one of the first all-girl bands in rock history. Stewart shares the screen with Dakota Fanning, who plays lead singer Cherie Currie.

What does Stewart think of playing a rock icon?

“I think my generation doesn’t really know what The Runaways was. I didn’t, even though I was aware of Joan Jett. She’s a legend, so it was a big deal not only to meet her, but to have her on the set. The main thing that Joan talked about was just how much she cared about that period of her life because it jump-started her entire career. The Runaways was one of the first all-girl bands, so it’s an incredibly triumphant, feminist story. Joan became my friend and I was thinking about all she stood for and going, ‘Oh God, now I have to do her justice.’”

As a matter of fact, Stewart did not fake anything from the vocals to the guitar. The young actress said she didn’t want to fake it, so she learned to play the guitar and worked hard to sing like Jett.

Catch The Runaways when it hits theaters on April.
