Kristen Stewart Talks About 'Twilight' Sexy Time

Well, what can you say? Sometimes, it’s the quiet ones you should watch.

It’s been a running gag among hardcore anti-Twi-Hards, how seemingly vacant and bored Kristen Stewart comes across as the polarizing “Twilight” saga protagonist Bella Swan. In fact, Beavis and Butt-Head had a few things about the subject in their maiden voyage back on MTV.

That being said, there’s apparently some serious fire raging under all that malaise!

Stewart told the UK Daily Mail recently that lensing the “Twilight Saga: Breaking Dawn” sex scene between Swan and real-life boyfriend Robert Pattinson as Edward Cullen really had the film’s editors working overtime to keep the “Twilight” climax below the R-rating line.

“It was so weird, it didn't even feel like we were doing a ‘Twilight’ film. I was like, 'Bella! What are you doing? Wow! What is happening here?!'” Stewart told Glamour.

“We totally have sex – finally!” she tacked on.

In fact, the film originally did get an “R” rating and needed a cut-down. Pattinson had his own moments that he apparently found particularly . . . amusing?

“I'm looking forward to the pillow-biting scene,” he said. “I thought that was so funny. Of all the random things to do, really? He bites the pillow.”

Stewart also cracks wise about she and Pattinson putting some extra miles on their respective legs jogging around the set to look in great form leading up to doffing their wedding duds and getting down to what sounds like the amusing business of vampire humpity-bumpity, which she claims already-shredded co-star Taylor Lautner found pretty amusing himself.

Um, that would be the jogging, not the humping, Pervy McPervpants.

She also talked about the surreal experience of heightened security and secrecy to keep pictures of Bella’s wedding dress from wandering onto the interwebs, which the Daily Mail likened to the security surrounding Princess Kate Middleton’s wedding dress.

When talking about sex, “Kristen and Robert” becomes a different story for Stewart, compared with “Bella and Edward.”

“People can say whatever they want…. [The interest] is totally understandable, but when it’s personal to you, it’s like your life becomes a product and I’m repelled by that,” Stewart said.

Totally.
