Kristen Stewart has let us into a little secret about the infamous sex scene in Twilight Breaking Dawn: Part One.

Kristen and real-life boyfriend Robert Pattinson had to act out the scene, in which their characters Bella Swan and Edward Cullen do the love dance for the first time, and Kristen admits a fair old amount had to be cut out.

Got carried away, did we?

Talking about the saucy scene on The Graham Norton Show, Kristen said: “It is a bit full on but it’s edited. I see scenes and I think ‘why is music playing over that’, I was definitely making sounds and it could be so sexy and it’s not.”

Kristen also gave us an insight into thrusting…

“The ratings' board breaks it down so technically and apparently, thrusting is a huge problem for the children,” she explained to Graham.

Twi-hards

While appearing on the show, Kristen also spoke about how the fans of the Twilight Saga – or Twi-hards as they like to be known – aren’t quite as crazy as we might think.

“I don’t have to deal with as much as you might think. People don’t scream at me on the street.

“That really doesn’t happen. I am getting better at spotting them. Their characteristics give them away. I really like them.”

Snow White And The Huntsman

Kristen’s been in London promoting her new film Snow White And The Huntsman, in which she plays the lead role.

Talking about a particular part of the movie where she has to 'rough up' her co-star Chris Hemsworth, she told Graham: “He’s a huge sex symbol so he needed a bit of roughing up!  It wasn’t too bad, I left a mark but he was able to keep working.

“I punched him right out of his close up. It’s funny now but when it happened I thought, ‘I have just ruined the movie and I love this thing and we are going to have to stop filming.’”

Crumbs. What we’d give to rough Chris Hemsworth up…
