A few HD caps of Natalie Portman
Beside Black Swan where, according to Mila Kunis
, Natalie danced her ass off, Closer is another movie where you can see Natalie's ass at work in a role of a professional dancer. Well, stripper actually.
Things get even better during one scene in a strip bar with Clive Owen in which one of her nipples magically appears for a few frames.
BTW, don't miss Natalie in Your Highness
for another chance to see her ass in a thong.
Closer is available on DVD, VOD and Blu-ray.
