Is That Kristen Stewart Dressed As An Army Officer?

The last time we saw Kristen Stewart, she was power dressing in Chanel at Paris Couture. Two weeks later and K-Stew has swapped the front row for a film set in Los Angeles. (Yes, that is her under the camo-print cap).

So - why is Stewart dressed in top-to-toe army gear? She's filming scenes for her latest role in Camp X-Ray and as she plays a military police offer, full camouflage print is required. Judging by that determined look on her face, something tells us that K- Stew likes being in uniform...

The question is, has she seen this dreamy behind-the-scenes pics from Robert Pattinson's Dior shoot yet?
