Kristen Stewart was spotted arriving in Argentina, South America to film On The Road for a few days in Patagonia.

The actress arrived at the Bs. As. International Airport and was accompanied by her co-star Sam Riley.

The Control actor looked very protective over his young co-star, guiding her through the airport and past the waiting paparazzi. What a gent!

Kristen must be finding being away from her Twilight boyfriend, Robert Pattinson difficult after they were reunited and closer than ever in Montreal last week.
