Agron: 'Pettyfer and I dedicated to new film'

Dianna Agron has revealed that she and rumoured boyfriend Alex Pettyfer shared a common enthusiasm for their upcoming movie I Am Number Four.

During an interview with Entertainment Tonight, Agron explained that both she and Pettyfer were dedicated to making director D.J. Caruso's sci-fi drama a compelling film.

"From the moment I met [Alex], he was really excited about the film and wanted to put the work in," she said. "It wasn't something where we both thought, 'Ah, this movie, we'll just sleep our way through it'... When you have two people that are eager to get in and see what it brings, it was great."

When asked to confirm whether she has begun dating Pettyfer, the Glee actress refused to comment.

"I never talk about those things," she remarked.

I Am Number Four, which is based on a novel by Jobie Hughes and James Frey, is released on February 18 in US and UK cinemas.
