Kristen Stewart arrived on the set of On the Road in New Orleans earlier today in her trademark skinny jeans and a t-shirt. She's back from a few weeks in Argentina to shoot scenes and sightsee during her downtime. Robert Pattinson was allegedly along for the romantic getaway after picking her up from her last shooting location in Canada. The two were spotted sharing a sweet kiss when they reunited up north, though their love is hot any season, not just the Summer. The two recently relocated from their LA hideaway, and Kristen's time in Louisiana can be a good scouting trip for their next spot since parts of Breaking Dawn will be filmed there. Cameras start rolling on the two-part Twilight finale this Fall, and most of you are eating up every detail Melissa Rosenberg will spill as she completes the anticipated scripts.
