Why do you keep falling for it?
Do you think a celebrity endorses a product because he or she uses it and really believes in it?
Do you think Delta Goodrem uses a Supermarket Shampoo on her precious locks at home?
Do you think Eva Longoria uses a do-it-yourself box of hair colour to dye her hair at home?
Do you think that Pierce Brosnan goes horse riding on a beach, then moisturizes his face before he shoots some pool with his mates?...

Because he's worth it!
It is all about money, money, money, and consumers support it.
You may say that they donate the money they are paid to charity though. If they do, is it still a noble thing to do?

They are helping to con you into buying a product to make a company money.

You could have donated money directly to a charity and it all would have all been put to use, not just 1 millionth of a cent from the sale of the product you bought.

What happened to integrity?
Some celebrities should care more about what influence they are having on the public.
They are paid to lead people into buying products that they themselves wouldn’t use at home, not even if the companies paying them, paid them even more money to do so.
