It is still speculative despite this' weekend photos, if our RobSten are indeed a couple. But here in "our world" it is hot and running! So help us to trace the steps back. Rob has openly admitted that he has a crush on Kristen even before they started shooting for Twilight. Well, of course our girl, Kristen had a boyfriend that time. So, when do you think, things started happening for these two? Give us your inputs and insights, so we can solve this RobSten puzzle together. I think it was during the New Moon shoot. What do you think?
