Jackson Rathbone Mum On Robert Pattinson/ Kristen Stewart Rumors

'It's none of my business. I stay out of it,' 'Twilight' actor says.

BOSTON — When we got the chance to talk to [movie id="369195"]“Twilight”[/movie] star Jackson Rathbone on the set of his new movie “Girlfriend,” we couldn’t pass up the opportunity to ask someone deeply involved the biggest question surrounding the franchise: What is the deal with Kristen Stewart and Robert Pattinson?

After a brief pause Rathbone carefully replied, “What’s the deal with them? Oh, they’re not actually vampires.”

Despite our faux disbelief that Pattinson wasn’t actually Edward Cullen, Rathbone insisted, “No, he’s actually a really nice human. It’s crazy, I know. I know. But yeah, the guy’s a great guy.”

Before “Twilight” had even debuted last November, there were rumors circling Stewart and Pattinson , with tabloids trying to figure out whether the two were romantically involved like their characters. And the fact that director Catherine Hardwicke said the reason she cast the pair was because of their potent sexual chemistry while doing a kissing scene on her bed — not to mention that Pattinson has admittedly proposed to his co-star four times — doesn’t help.

“Everybody always asks me those questions about that, and it’s one of those things — it’s none of my business. I stay out of it,” Rathbone said.

But despite the relative silence from the cast on the subject, tabloids — like OK! magazine this week — continue to cover supermarket checkout aisles with conflicting testimonies regarding the actors’ relationship status.

“Whenever we’re passing through the tabloid articles, we’re always like, ‘Hey! There’s our friends!’ ” Jackson said with a laugh. “I’ve been able to stay out of them as much as possible.”
