Kristen Stewart, Dakota Fanning Defend Drug Use In 'The Runaways'

"I've been exposed to everything under the [sun]," Kristen said of her own upbringing, implying that teenagers are smart enough to see other people's mistakes and not necessarily follow in their footsteps. "I think that if you don't realize the people you look up to [are just acting, that's a problem]. This is also a really hard question for me."

The fact of the matter is, when the film hits theaters March 19, fans will be watching two actors portray rockers Joan Jett and Cherie Currie — real-life people who participated fully in the sex, drugs and rock and roll of the mid-'70s. Some, however, will inevitably find it difficult to see Jett and Currie instead of Stewart and Fanning.

"This is [about] real people," Fanning said, defending the scenes. "This is their real experience.

"It's the story," she added. "[Us doing drugs] is just about finding the beats, you know what I mean?"
