The original sex scenes between Kristen Stewart and Robert Pattinson in The Twilight Saga: Breaking Dawn - Part 1 were much too racy for moviegoers, according to the film's leading lady.

"We originally got rated R," Stewart, 21, tells the December issue of Glamour UK. "They recut it."

The headboard-breaking, pillow-biting honeymoon romp was a new experience for Stewart and her real-life love, 25. "There are two big sex scenes in the two [final] films, and we did them fairly early," she says. "It was so weird."

"It didn't even feel like we were doing a scene within a Twilight film," she explains. "I was like, 'Bella! What are you doing? Wow! What is happening here?!' It was very surreal."

Stewart says the watered-down theatrical version makes sense, given the Twilight franchise's younger fan base. "[The ratings board] knows who our audience is, and can be like, 'Hmmm guys, just cool it a little.' It's funny because in the book, you don't see anything. It's everyone's imagination, so it's entirely subjective. I hope it's good!"

The actress adds that she was equally nervous when the time came to film the highly-anticipated wedding scene.

"I had to be shrouded in secrecy the entire two days of filming. It was crazy," she laughs. "I was on full lockdown, as if I was wearing millions of dollars worth of diamonds, and I'm so excited for the wedding dress to be revealed.

"It was one of those moments you go, 'This is something to remember,' and you want to put yourself in the experience so that it doesn't pass you by," she gushes. "It ended up being great for everyone, I think."
