The German beauty, 36, admits she is a big fan of both the vampire books and the movie franchise, so she immediately accepted when she was offered a role in the sci-fi drama.
She tells Us Weekly magazine, "I love Stephenie's books - so many emotions! She appeals to my inner teenage girl... Obviously, I've seen Twilight. I'm Team Edward, for sure! It's fun to be part of the cool kids' club!"
Kruger has been on a promotional tour across the U.S. for the film and she has been flattered by all the attention she's received from adoring male fans.
She says, "I didn't quite realise what a devoted fanbase Stephenie has and we did a couple of poster signings in malls around America and thousands of people showed up. It's actually neat because I don't make teenage films, so I get asked out on dates, I get presents... I'm totally ready for teenage boys!"
However, they'll all have to line up behind her current boyfriend Joshua Jackson.
