Robert Pattinson & kristen Stewart are pretty adorable together. More in a brother&sister kind of way than as star crossed lovers. From this, I´d think Rob has or has had the major hots for Kristen and she´s being good about it, hazing him a little.

Kristen Stewart seems a sensible, grounded girl, I like her (hope she looses that hairdo right quick though). That´s why I think they´re probably laughing their heads off at all the “are they/aren´t they”-rumors.
I must say Rob´s been more eloquent, he desn´t even finish one single sentence other than “shut up!” (which was funny) I can imagine being asked the same inane questions over and over again, you start admiring each others´nail polish (as Kristen does).
