Robert Pattinson, Kristen Stewart's 'Breaking Dawn' Sex Scene Goes 'Ghost' Protocol

Edward and Bella's vampire-on-vampire action is 'a third form of sexuality,' Pattinson tells MTV News.

You've seen them lock lips. You've seen them break headboards. But now that they're both vampires, Bella Swan and Edward Cullen are about to discover a whole new "form of sexuality," the stars of "The Twilight Saga" tell MTV News.

"Twilight" comes to an end when "Breaking Dawn Part 2" hits theaters on November 16, and with the saga's conclusion comes the culmination of Edward and Bella's physical relationship. After the events of the first "Breaking Dawn" movie, the newly minted Mrs. Cullen is now a vampire — just like her husband — leaving fans to wonder just how hot and heavy the happily married couple are about to get.

But the vampire-on-vampire action might not necessarily be as steamy as it would seem on paper, to hear the stars tell it.

During "MTV First: 'Twilight: Breaking Dawn - Part 2,'" series leads Robert Pattinson and Kristen Stewart were asked to tease the fans on what to expect from their vampire-on-vampire romance, something that Pattinson described as "a third form of sexuality."

"Oh, I can't wait," their co-star Taylor Lautner laughed when the question was asked. For her part, Stewart was happy to let her leading man field the question.

"I'm going to let him take this one," she decided, putting Pattinson in the hot seat.

Pausing for a moment to find the right description, Robert finally allowed that while he has yet to see the scene for himself, he can only imagine it has something in common with one of the most iconic love-making scenes in cinema history.

"I haven't seen it yet, so I don't know, but I imagine it's quite like the scene where they're doing pottery in 'Ghost,'" he teased, drawing laughs from his co-stars.

They can laugh all they want, but if Edward and Bella's relationship is about to hit Patrick Swayze and Demi Moore heights, then fans are much more likely to swoon than giggle come November 16!
