Robert Pattinson and Kristen Stewart Harper's Bazaar Photos

Twilight co-stars Robert Pattinson and Kristen Stewart ooze intense chemistry as they pose together for a photo spread to be featured in the December 2009 issue of Harper's Bazaar.

The rumored lovers chatted with the mag about relationships, romance and self googling. Check out some highlights:

Kristen on Robert's qualities: "He's a great singer. Heartbreaking.I'd have to say Rob is [more romantic]. I think romance is anything honest. As long as it's honest, it's so disarming."

Kristen on her nickname for Robert: "I'm definitely claiming that one [that I'm more athletic]. Rob can barely jump rope. I call him Flippy because when he does his stunt rehearsals, he flips around [makes gestures like a penguin]. And God, when he tries to run."

Robert on Googling: "[Kristen] would say me, but I reckon it's her. If either one of us catches the other one doing it, we're like, Jesus Christ, is that what you're looking at? And the other one's on their phone pretending to text. I look up my competition more than she does. I'm incredibly shallow. I think she just looks at herself."

Robert on how most of his previou relationships end: "Eventually, the girl is like, 'I know it's got nothing to do with me. You're an. . . idiot.'

Rob on who's more superstitious: "I am. I believe a lot in karma and stuff. Like when I end up with egg on my face, I'm like, Fate! I was born doomed. But I think it's more being an idiot than superstitious."
