Alyson Stoner steps it up with costar Sharni Vinson as they premiere their new flick, Step Up 3D, at the El Capitan Theatre in Hollywood on Monday night (August 2).

The 16-year-old actress caught up with JJJ on the red carpet and shared with us about the most difficult part of the movie for her: having a romantic interest!

Alyson shared, “I’ve never had to experience that before. Thankfully, I’ve known Adam [Sevani] for eight years and we’re very comfortable with each other. Our chemistry and our friendship was just already there. It wasn’t that awkward though. I had to put on a face that was a little doe-eyed, madly in love kind of look and that’s something that I never had to do before.”
