Movie stars are frequently caught without makeup (by naughty paparazzi, clearly without makeup and any primping).  A movie star’s look is the magic of Hollywood.  FYI, the Paparazzi will try and catch a movie star unprepared and enjoying his/her right not to wear makeup, etc., and the tabloids may have even photoshopped the photos to make a movie star look even more disheveled.
