TWILIGHT couple R-PATZ and K-STEW finally get their groove on in the fourth flick of the franchise. Those brooding glances and lust-fuelled embraces will finally result in some nookie. Real-life couple Robert Pattinson and Kristen Stewart will film their first sex scenes as vampire Edward Cullen marries mortal Bella Swan. Kristen said: "It does actually literally get more physical (in Breaking Dawn). "It doesn`t get more action-packed... (but) they definitely get more physical. Well, they get married. "They`re man and wife now. They have a kid and stuff too, so, I guess to get there that happens. "We totally have sex - finally!"
