Robert Pattinson Arriving in LA

Robert Pattinson wore his favorite baseball hat and held on to a small carry-on making his way through LAX today. The Twilight star is in Hollywood readying for tomorrow night's MTV Movie Awards, where he's expected to reveal the first full-length trailer for Breaking Dawn with costars Kristen Stewart and Taylor Lautner. We got a sneak peek of Edward and Bella's wedding scene last week, and hopefully we'll finally get a glimpse of the couple's sexy honeymoon. Rob's been in Canada for the past week filming Cosmopolis and sweetly posing for photos with his adoring fans. There's a good chance his fans voted for Rob and Kristen to win the best kiss category at this year's awards, but we'll have to wait and see if they pull off a three-peat — join us tomorrow where we'll be streaming live coverage from the red carpet at the MTV Movie Awards!
