Kristen Stewart [photos] says shooting sex scenes with real-life boyfriend Robert Pattinson was surreal.
In fact, the scenes were so steamy that the MPAA originally gave the film an R rating, according to the 21-year-old.
"We originally got rated R," Stewart tells 'Glamour UK'. "They recut it."
"There are two big sex scenes in the final two films, and we did them fairly early," she explains.
"It was so weird, it didn't even feel like we were doing a scene within a Twilight film. I was like, 'Bella! What are you doing? Wow! What is happening here?!' It was very surreal."
"The MPAA knows who our audience is, and was 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!"
Meanwhile, Robert Pattinson recently revealed that 'Twilight: Breaking Dawn' used a real priest for the wedding scene.
"The wedding scene's funny because we used a real priest. So technically we are already married because he did all the things you would do in a normal ceremony," Pattinson laughed at a press conference in Sweden.
"So we don't have a civil union in law, but I guess in the church we are actually married."
