Celebrities so careful about their image, why?

Have you noticed how most celebrities are extremely careful about their image. Actually image is everything and it is what causes people to purchase from you. But even more important to note is that the wrong image can be extremely damaging to you and your home business. At best it will entice many to buy but when they discover that there is a lie being told somewhere they will quickly disappear, probably forever, from ever patronizing your business again.
