Robert Pattinson carried his own bag yesterday when he arrived at LAX. He's in California once again after spending a couple of weeks with family and friends in the UK. Robert and girlfriend Kristen Stewart were able to have some fun nights out on the town together, including an evening with their pal Tom Sturridge at a Marcus Foster concert. Kristen was busy during the days, though, completing work on her upcoming movie Snow White and the Huntsman. Robert and Kristen have been celebrating the runaway success of their latest Twilight movie, Breaking Dawn Part 1. The movie has grossed over $500 million in worldwide box office, and now the studio behind the picture, Summit, has won in the courtroom. Summit sued a company making "Bella Swan" jackets without a license, successfully claiming that the sales pitch infringed on their copyright.
