If there’s one thing we’ve learned about Dianna Agron (Quinn), it’s that she’s just plain nice. So it goes to reason that her boyfriend would be nice too, right?

Pretty much. “Alex [Pettyfer] might see himself as a bad boy, but he's actually very sweet in real life," she tells Sugar. "And I think it's important to have your differences in any relationship. I wouldn't want to be dating a carbon copy of myself. That would just be boring."

Dianna co-stars with Alex in I Am Number Four, and apparently their relationship started very early on in the process. "The film's director [D.J. Caruso] basically set us up. He was like, 'Maybe you should meet this guy before you're forced together in front of the cameras.’ So Alex and I met for dinner, and I was really worried that it was going to be awkward, so I brought along my dog to break the ice. Within minutes this huge German Shepherd was up in Alex's lap, licking his face. It was so funny!"

The rest, as they say, is history.
