Kristen Stewart &Dakota Fanning On Acting Vs. Rocking

Which is more awesome, being a rock star or a Hollywood star?

"Hmmm," pondered Stewart, who, thanks to the "Twilight" films, is arguably hotter than any actress in Hollywood at the moment. "What's cooler?"

"I enjoy being an actor pretending to be a rock and roll star," Fanning laughed.

"It's like the best of both worlds," KStew agreed.

The same could probably be said of these two actresses. These days, they've made back-to-back films (Fanning joined the "Twilight" saga for "New Moon" as the Volturi vampire Jane) and are so close in age and friendship that it seems like they could keep making movies together forever.

Previously, however, their careers were quite different: Stewart was known as an actress of great promise who already seemed grown-up beyond her years, while Fanning spent a half-decade as the ultimate adorable moppet in films like "The Cat in the Hat," "Dreamer" and "The Secret Life of Bees."

Now they've rocked Sundance as the Runaways. And what do their hands-on parents think of seeing them as hard-partying, drug-abusing punks?

"My mom has seen it," Fanning said a bit sheepishly.

"Nobody's really seen it for me," Stewart replied. "I don't know yet."
