Kristen Rocks Out as Joan Jett

She's revealed a glamorous side recently during London Fashion Week, but PEOPLE.com has a first look at Kristen Stewart channeling her inner rocker – Joan Jett, to be precise – in her upcoming movie, The Runaways.

In the scene, Stewart rocks out in her bedroom after her band, the Runways, breaks up.

The movie, which arrives in theaters on March 19, is a coming of age story about the all-girl rock group. It also stars Dakota Fanning, who plays Cherie Currie.

The actresses premiered the film at the Sundance Film Festival last month, where they cheered on Jett and her band the Blackhearts during a lively concert, even joining them on stage at one point.
