since she is a publically known figure she doesnt need to sign a realase. Everyone knows who she is and her age. the 2257 is just so she isnt underage...
why do you think magazines can get away with posting pictures of sheer blouses and stuff like that of celebs? they never sign a release. I cant explain it well, but it has to do with celebrity. Its basically too fucking bad if they do something dumb and someone prints it since they are always in the publics eye.
