Actor Robert Pattinson admits that filming sex scenes in ‘Twilight Saga: Break Dawn – Part 2’ with real life girlfriend Kristen Stewart was “ridiculous”. The 26-year-old recently rekindled his romance with the actress after she cheated on him with director Rupert Sanders. “The sex scene in this one is pretty ridiculous as well…you`re trying to think of things to make it sexy, it`s supposed to be about the greatest vampire sex you`ve ever had. You try and give a face of ecstasy; guy`s faces I don`t think are really designed to do that,” contactmusic.com quoted Pattinson as saying. The film is the final installment of the ‘Twilight Saga’ franchise.
