We could care less about whether or not Natalie Portman can dance, but we are extremely skinvested in the following question: is that really her ass? Irish model/actress Caroline Davis (pictured at left), soon to be seen as a medieval hooker in the HBO series Game of Thrones, is claiming that the thong shot heard 'round the world was not actually Portman's port hole, but hers.

In the beginning of the scene, Natalie's face can clearly be seen as she takes off her dress to reveal thong and bra, so it's safe to say the booty in that shot is all Natalie. But sources close to the production told FilmDrunk, who broke the story, that the shot where Isabel dives into the water used a "stunt double." Or, in this case, a butt double. Our apologies, Caroline- our cheeks are almost as red as yours are creamy white!
