Robert Pattinson paid a visit to 'Twilight' co-star Kristen Stewart on the set of her new movie 'On the Road' in Montreal, Canada on Thursday.
The two are rumored to be a romantic couple, but no one knows for sure. New photos show the couple getting awfully close near Stewart's trailer, but no one has ever caught them locking lips.
Pattinson had another reason to visit the 'On the Road' set. His best friend, Tom Sturridge also has a role in the film.
