Here's an excerpt from the interview where she discusses Kellan:
Plus, you got to kiss Kellan Lutz. Kellan is such a sweetheart, and was so lovely to work with. Plus, I mean, well, I'd never complain about showing up to work every morning to work with a handsome man. I loved seeing Kellan every morning, but I'm not sure my husband loved it!
And every teenage girl in America... He's a lot of fun to have on a movie set, and so incredibly nice. I'm glad I got to work with him, but I also felt bad - he was filming our movie, and filming [Twilight] so he was running back and forth between every set, and the boy did not have a day off.
Were you ever worried that Kellan would start saying vampire lines on set? Ha! No, he was very focused the whole time. He was great.
