Kristen Stewart may play a rock star on screen, but has admitted she isn't one in real life.
The Twilight star, who portrays Joan Jett in her new film The Runaways, really admires the 70s musician's rocking swagger.
"If I had that drive... It could never be fun for me to be a rock star because I'm not one," she told US talk show hosts Regis Philbin and Kelly Ripa.
Kristen, who will reprise her role as Bella Swan in The Twilight Saga: Eclipse, had to study Joan carefully to ensure she does her justice on the big screen.
"Yeah [I felt some pressure], especially for the performances because she has such a distinct voice," she said.
"She is on fire. She stares the audience down. I've never seen anything like it and you don't know you can do it until you do it for the first time." ( source: Press association)
