Kristen Stewart On Reuniting With Robert Pattinson For 'New Moon': 'It Was Easy'

"Twilight" stars Kristen Stewart and Robert Pattinson share a lot, from magazine covers and taste in music (Kings of Leon, anyone?) to a romance (if the tabs are to be believed). But in behind-the-scenes footage from the set of "New Moon," Kristen divulged something else the pair has in common: a similar acting style.

"We're both pretty instinctual, impulsive actors," she explained. "We don't really hash things over, over and over because we both know our characters very well."

In fact, the two are so well acquainted with lovesick Bella and melancholy Edward, that it was as if no time had passed between the filming of "Twilight" and its sequel. "It was pretty easy to step back into the project," Kristen said. "Once you play someone, it's a strange thing, you don't forget who they are." It's also doesn't hurt to have a costar you enjoy working with. "We work together well," she added. "So it was easy."
