'Twilight: New Moon' stars Kristen Stewart, Taylor Lautner talk breakups

Without spoiling too much, we can tell you a killer breakup is at the core of "New Moon," the second movie in the "Twilight" series.

That led stars Kristen Stewart (who plays human teen Bella) and Taylor Lautner (in the role of werewolf Jacob Black) to tell MTV just how rough it was to ramp up the normal breakup process to "Twilight" levels. Because when you're in love with a vampire, everything's heightened.

"It's like, people don't just break up [in the 'Twilight' films] -- they break up and it literally kills you," Stewart tells MTV. "It's not like you just say, 'Oh, I'm really depressed and crying.' Everything is supposed to be a fantasy version of that. So I always had a really hard time figuring out, 'Am I doing enough? Do I look like I'm going to die?'"

Lautner, in the role of a werewolf pining for a human's love, says he didn't get off any easier: "[Bella] goes into this depression, I come to try and bring her out of it. Then I go through my own issues, and then she leaves me. It's all over the place, and there's a lot going on."

Frankly, we like the chemistry we've seen so far between Stewart and Lautner. The two have a playful, natural rapport in contrast to the overly emo tortured-looks relationship between the characters of Bella and vampire Edward.
