Robert Pattinson says he was \"scared\" when he had to film an intimate scene with girlfriend Kristen Stewart for Twilight Saga: Breaking Dawn — Part 1 because it was done in such a complex set-up. The 25-year-old and Stewart performed a raunchy scene in the movie and the actor admits he felt more distracted looking for his cue rather than romantic. \"I\'ve never done a sex scene where it\'s kind of scary because you think something is going to fall on you! There was a whole stunt set-up with three guys, who do all the explosions and things, all lying under the bed. I spent the whole time looking at them for a signal. It was funny, though,\" contactmusic.com quoted Pattinson as saying. From: Gulfnews
