Robert Pattinson, Kristen Stewart's night out in Vancouver

If sources are to believe Twilight stars Robert Pattinson and Kristen Stewart have recently spent a night together in a same room in a hotel. After filming the Twilight sequel Eclipse in Vancouver, they rushed into their room at celebrity hotel Chateau Marmont, on Sunset Boulevard in Hollywood.

Sources claim that the duo entered the room, they did not come out for the whole night "They went straight up to a room. No one saw them the rest of the night," the E! Online quoted a hotel source as telling.

Even though the pair has been spotted together many a times in hotels and on outings, they are consistently saying that nothing is cooking between them. They claim that they are just friends and they are characters in a comic book. Why they are not coming out publicly about their love affair? What are they bothered of?
