(Cover) - EN Showbiz - Nikki Reed believes the romance in Twilight is "magnetic".

At a screening of new movie The Twilight Saga: Breaking Dawn - Part 1 at the Rome Film Festival on Sunday Nikki, who plays vampire Rosalie Hale, shared her thoughts about the franchise's central love story.

The film follows vampire Edward Cullen and human Bella Swan as they embark on married life.

"This love between Edward and Bella is just out of the realm of possibility and reality," she told Access Hollywood. "I mean, it's unattainable, it's not real, and that's what makes it so magnetic."

The star believes the movie appeals to women of all ages.

Nikki thinks all women strive for a love like Edward and Bella's.

"That's why there's no specific demographics for this, because you know, 12-year-old girls fantasise about having this, and women in their 40s, 50s, 60s, think about when they had that first love," she revealed.

However, her co-star Jackson Rathbone struggles to understand the franchise's appeal. The actor plays vampire Jasper Hale in the movies.

"When I first came on board of Twilight, I had no idea what was going to happen with it, and for it to be now a worldwide phenomenon is still baffling," he confessed. (C) Cover Media
