15-year-old Dakota Fanning brings downtown cool to Sundance, wearing black dress accessorised with an asymmetrical Alica + Olivia jacket and fingerless gloves at the premiere of her new movie The Runaways.

The film charts the rise and fall of one of the first all-female rock bands and also stars Twilight actress Kristen Stewart. The young stars deliver impressive performances as Valley girls-turned-rock icons Joan Jett and Cherie Currie.

With provocative costumes, underage drinking, drug use and sex, The Runaways will likely catapult the actresses out of teen queen status. But neither appears very concerned about alienating fans. There’s also a drug-fuelled kiss between Kristen and Dakota about midway through the film that will likely help them shed their image – and do absolutely nothing to quiet the film’s buzz.

“It wasn’t that big of a deal,” Dakota said. “It’s just another part of the story.”

Looks like our baby’s all grown up now!
