No, a Rob Pattinson fan did not make their way to the set of Kristen Stewart's new film and punch her in the face...

On Friday morning K. Stew was snapped shooting scenes for Camp X-Ray in Los Angeles, and the 23-year-old starlet had a bit of fake blood on her lip. Wonder which one of her co-stars she has an onscreen squabble with?

This is her first movie since Breaking Dawn Part 2, and she'll play a U.S. solider stationed at Guantanamo Bay. The film also stars Lane Garrison, who has been trying to build up his career after spending nearly two years in prison for a drunk driving accident that killed a teenager in 2006.
