(Cover) - EN Showbiz - Justin Bieber is a fan of hit teen movie franchise Twilight.

The pop star was asked to choose between the popular vampire saga and the equally popular Harry Potter series, but struggled to make up his mind.

Justin, whose movie Never Say Never won Best Jaw-dropping Moment at the MTV Movie Awards last night, had to think hard before choosing Twilight.

"I can't say!" he told MTV, "But if I had to choose Twilight over Harry Potter."

The teen heartthrob also revealed that it felt amazing to share the moment that bagged him the award in his 3D movie.

Never Say Never follows the pop star's journey to the top and shows some breath-taking scenes of the 17-year-old performing.

"It felt great," he said. "Obviously that was my first performance at Madison Square Gardens [in New York] and just to have that experience it was great." (C) Cover Media
