Robert Pattinson: New Moon Breakup Was the Best

Swoon alert: Robert Pattinson, Kristen Stewart and Taylor Lautner made appearances at San Diego's Comic-Con 2009, hitting the red carpet and a press conference.

While Rob and Kristen appeared a little cold towards each other at first, an eyewitness tells OK! the twosome warmed up as they answered questions about the film.

Sure they did.

Robsten "had their guard up," says the onlooker, but body language doesn’t lie - when asked about their chemistry, Rob blushed and a smile lit Kristen’s face.

We are totally just moments away from Kristen seducing him.

Here's a New Moon Comic-Con photo of the three stars ...

As the the mood lightened, Kristen’s attitude towards both Robert and Taylor “was very playful.” The two studs then made faces at each other. Like, OMG!!

While recent tabloid reports have been dominated by stories about Kristen and Rob and how he "really wants her," today's press conference focused on the film.

Interestingly enough, when asked to describe his favorite scene, Robert Pattinson picked one of the saddest - New Moon spoiler alert! - when Edward leaves Bella.

“I think my breakup scene was my favorite scene,” he revealed. “Hopefully it will come off as having quite a few more levels than the relationship in Twilight.”
