Here's the part from that interview that got everyone excited:
Everyone is talking about whatever is going on between Robert Pattinson and Kristen Stewart. Is that good for business?
Do you want the honest answer? I haven't even thought of it that way.
That's not the honest answer.
It really is. I honestly don't think of it in terms of business. It doesn't affect our core business at all. The thing I do think about is, Oh my God, I hope they stay together. Because it could be awkward on set in the next movie if they have a huge falling out. It's like, Wow, they have to portray this love story through two more movies. God, I hope they stay together; please stay together. That's what affects my day-to-day.
But you walk by newsstands and it's a publicist's dream: they are on every cover.
I don't feel it's out there anymore. Do people still report on it? If you look at people who have a stable personal life, the rags get tired of them. I think we're heading to that place where they are together and that's their life and we better find someone new to create drama out of.
The way the interview went, it seems Godfrey had accidentally let the 'truth' slip. In saying that his interest in the Kristen-Rob romance was that they stay together so there would be no awkwardness on the set, the obvious premise was that the two were already indeed together. He then suggested that he didn't think the real score between Kristen and Rob had much impact on his most-successful franchise ever, because the tabloids were no longer interested in them as what they had was already stable.
But was Godfrey that innocent? Was it possible for him not to know that the real score between the two stars had been the subject of intense speculation in the fan base, which is the main market of the franchise? Did he honestly not see the publicity potential there just a few weeks short of the opening? Seems suspect.
Which is why, to answer the question in the title line, I say I don't know, and I don't care. If they're indeed together and have, as Godfrey said, built something stable between them, good for them! But they're actors. They're not Bella and Edward.
I'd only be interested if a fanfic twist emerged from this issue, such as Rob is actually a real vampire playing a vampire, and fell in love with his dark and emo co-star Kristen because her blood smelled so sweet. And after the Breaking Dawn shoot he will turn her, and they will live together and have hot, mad sex daily for centuries to come.
