Kristen Stewart Heads to Work at

Arriving on the set of her new film, Kristen Stewart was in Los Angeles shooting “Camp X-Ray” on Thursday (July 18).

The “Twilight” star dressed casually in gray with a zip-up sweatshirt, tank top, and cotton pants as she puffed on a cigarette outside.

In the drama, set for a 2014 release, a soldier assigned to Guantanamo Bay befriends a man who has been imprisoned there for eight years.

Joining the 23-year-old actress in the movie are Lane Garrison, Joseph Julian Soria, Peyman Moaadi, and Tara Holt.
