Dakota Fanning may only be fifteen years old, but the actress has already worked with the likes of Sean Penn, Robert DeNiro, Denzel Washington, and Tom Cruise. So what else was left for her to do? Get involved in a major franchise! Dakota talked about her latest project and transitioning into being an adult actress with Teen Vogue.

Dakota will do that this month as the Volturi Jane in 'New Moon.' Jane has the power to cause pain without even touching her victims. Ouch! Dakota said she didn't need to do much to prepare for the role: "The red contacts were enough."

It wasn't a hard sell to get Dakota to sign on; she's a major 'Twilight' fan.

"I read all four Twilight books in one week. It's such a phenomenon, and I wanted to be able to say that I was a part of it."

Shooting 'New Moon' also gave Dakota a chance to get to know 'Twilight' star Kristen Stewart before they started shooting their film 'The Runaways.'

"We became really close," Dakota says, "like we'd known each other for our whole lives. We talk all the time.

"I've never been such an evil character, and because I do know Kristen so well, being mean to her was really weird. It's like, Sorry, dude!"

Kristen apparently feels the same way. In an email from the 'Eclipse' set, she told Teen Vogue:

"Dakota is one of the most consistently moving actors I have ever worked with. I'm always better with her."

Sounds like high praise from one actor to another! You can read more of the Teen Vogue interview here, and get a copy of the December/January issue when it hits newsstands on November 17.
