If Joan Jett gives the stamp of approval it must be a good thing.
Joan Jett is thrilled to hear Twilight star Kristen Stewart will play her in an upcoming biopic - because she thinks the actress has the "right energy" to play the part.
Stewart will play the I Love Rock & Roll hitmaker in new film The Runaways, and the real Jett couldn't be happier.
She says, "When her hair is cut and with the right make-up, Kristen should make a really good me."
The odd couple has already had a chance to jam together, and Jett is impressed with the young star's musical skills: "She sounded great and played well.
"She has the passion for it, which you can't really be taught."
