Are you persuaded to buy celebrity endorsed products/brands?

Does P-diddy representing "CIROC" make you want to go out and buy this "exclusive" alcoholic beverage? Does Paris Hiltons face make you want to purchase perfumes and beauty products? Are you willing to purchase products simply because they are endorsed by celebrities? Do you find yourself purchasing JLO, hillary duff items? If so WHY? I myself refuse to purchase anything which is endorsed by celebs.
