Jessica Simpson in Short Shorts

Jessica Simpson goes for a jog in a pair of short shorts Thursday on the set of Major Movie Star shooting in Beverly Hills, Calif. She looks much more… real that she usually does.

In the film, Ms. Simpson, 27, plays an actress who is forced to join the military. Yesterday, Jessica was seen looking homeless and taking to the bottle as shot a few other scenes.
