Robert Pattinson dragged his luggage behind him outside of LAX today. He had help carrying his guitar, though, as he made his way to a waiting car. Rob's back in LA after spending a week in London where he was seen walking around Notting Hill solo during a late night out. He may have had a chance to see girlfriend Kristen Stewart while overseas, since she's there filming Snow White and the Huntsman, but the couple weren't spotted out. Rob and Kristen are together in the latest Breaking Dawn trailer, which features new scenes of Edward and Bella's honeymoon and Bella's pregnancy. It's a dramatic look at the upcoming film; though, we'll have to wait until November to see Part 1 on the big screen.
