Robert Pattinson and Kristen Stewart were spotted going through security at LAX on Thursday. They headed out of town together to take care of reshoots for Breaking Dawn in the Caribbean after wrapping up work on the project in Vancouver last week. The on- and offscreen couple have already returned from the trip since Rob was seen catching a flight out of St. Thomas just yesterday. It was a big weekend for the star following the release of Water For Elephants on Friday. The movie didn't grab the number one spot at the box office, though fans of Rob and Reese Witherspoon still seemed excited about their big-screen effort.
