celebrity's know its their life and its public. thier privacy becomes sacred because its somthing that dosent happen often. but being a celebrity means being known to the public and thier life becomes public. they can choose to hide it, or use it, but either way it eventaully is known. it's all part of the deal, you get rich u get famous and u lose somthing in return. ( as u can hide and eventually end up on the show 'where are they now' for being secretive) it's a tough world ...
