A bare-faced Jessica Simpson failed to hide her make up-free mug as she stepped out for a day at the studio in Beverley Hills.

Dressed down in baggy sweat pants and trainers, the wannabe country star clearly wasn't ready for her close-up and attempted to hide under a pair of red shades.

Accompanied by an assistant who tried to shelter Jess' low-maintenance look from the cameras, the Dukes Of Hazard actress looked less than pleased to have been caught without her slap on.

But Jees needn't have worried - she actually doesn't look half bad minus the usual layer of warpaint.
