I believe that the photographer owns the copyright.

There might however be obligations owed by the photographer to the model in such a scenario. I imagine that it could be deemed a 'breach of confidence'[1] and there may be specific privacy laws in some jurisdictions.

Also for this specific case of nude pictures I imagine you could quite quickly get into harassment/cyberstalking territory.
