Shauna Sand's John Hancock -- A Fake?

The sex tape starring Shauna Sand is being delayed a week -- and it all has to do with whether or not Shauna signed on the dotted line.

Vivid Entertainment says it plans to counter Shauna's cease and desist letter by bringing in a handwriting expert to prove the release they have is authentic. Fun fact: if it is, it could be the only thing about Shauna that is truly authentic.

No word on how long it will take the handwriting expert to draw a conclusion -- but how hard can it be to analyze an X?
