How do we know who twit? or tweet? When a celebrity has an official web page, we can be fairly certain that what is posted there as the core content is by their own authority. How do you do that with tweets?
Some celeb accounts are verified. Also, if the twitter feed is linked from their official web page, you can be reasonably confident it's theirs, if not them personally!
