I wrote a couple months ago about "holding onto old photos for an opportune time to release them." There are many reasons to release the photos now of Vanessa Hudgens, beginning with:
1. maybe to break free from a bad contract with disney
2. spite by the photographer / lover / boyfriend
3. someone who wanted to make a lot of money selling the photos of a nude vanessa hudgens of high school musical fame.
One last question is, did zac efron take the nude photos of vanessa hudgens in her bedroom?
take a look at my other article on the subject of selling photos that were held onto.
