Celebrity Nudity

Why are we so obsessed with seeing a celebrity nude? If for instance Britney Spears was not famous, would we be so interested in her nude body? What makes them so special?

Are celebrities more attractive perhaps? There are so many stunningly beautiful people out there, yet they don't get the same attention as a celebrity, so I would say no.

Or is it a bit of curiosity? This might be true as celebrities that have not bared all seem to get more of this type of attention than those that do regular nude scenes. If ths is true then might we as a society become a bit more mature about nudity, if it where a more common occurance?

Just a thought. :)
