Dakota Fanning pumps up the volume on the January 2010 cover of V Magazine.

In the sneak peek of the issue, which boasts plus size models, the 15-year-old actress dishes on her upcoming flick, The Runaways. Dakota shared, “I really enjoyed doing that subject matter for the first time in a biopic, because it really happened, it’s not just a made-up story about a 15-year-old running wild. It’s a true story of her evolution from good Valley Girl to bad rock ‘n roll princess.

Dakota also shared about on-set bonding with Kristen Stewart, especially about the kiss. She said, “[The kiss] It’s passionate, they were just as close as two could get. [The drugs] It’s actually crushed B vitamins. Kristen and I were, like, our hair is gonna grow a lot from these.”

The January 2010 issue of V hits shelves on Thursday, January 14.
