- Nude Model: A girl who posed without clothes for pictures or sometimes video.
Nude model is an interesting category because it covers everything from non-nude teaser girls being nude but not showing anything at all all the way up to spread pussy shots. It really depends on context. For what it's worth, the Kim Kardashian pictures from the recent Magazine shoot with her ass and tits on display make her a nude model - and her home sex tape of course makes her a pornstar! Many girls will do nudes or "implied nudes" but never will do porn. For others, nude modelling is the first step towards getting boned on camera.
