Robert Pattinson arrived at LAX last night carrying one bag and getting some help with the rest of his luggage. Robert spent Christmas in England with his family, but is now back stateside to celebrate New Year's Eve hopefully alongside his girlfriend Kristen Stewart. When they weren't promoting Breaking Dawn Part 1 around the world, the twosome were both in London for much of the past few months while she shot Snow White and the Huntsman. Their promotional tour and cohabitation meant many sweet moments from Robert and Kristen. It was no surprise, then, that the Twilight pair scored big, winning a number of our best of 2011 polls, including sexiest couple and favorite PDA moment.
