New Moon's Robert Pattinson & Kristen Stewart grace the December cover of Harper's Bazaar and share the wild ride that has catapulted them into the spotlight for better or for worse. The magazine gets an inside look at the life of Hollywood's hottest young stars and in the interview the two share their thoughts on each other -- and why Stewart's nickname for Pattinson is Flippy.

Harper's Bazaar's December issue hits stands November 17th.

Stewart calls Pattinson "a great singer. Heartbreaking," while Pattinson says of his costar, "She's a unique girl. You really don't meet many people like Kristen."

When asked who is more romantic, Stewart immediately says Pattinson, adding,

"I'd have to say Rob is. I think romance is anything honest. As long as it's honest, it's so disarming."

When is Pattinson posed with the same question he quips,

"What did Kristen say?" When he finds out that she pointed at him, he responds, "No. I'm better at faking" and laughs.

Pattison on Stewart:

"Kristen doesn't take an slack. She sticks to her guns - and that's difficult to do."

Stewart on who is more athletic:

"I'm definitely claiming that one. 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..."

Pattinson on who googles themselves more:

"[Kristin] 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."

Love these two!
