Celebrities are over: they do not represent anyone, but themselves and they are obsolete as the new values are raising interests in people's mind.
Moreover new concepts as sustenabilty and respect for mother nature are in need of new testimonials among normal persons.
No Lady Gaga, no Miley Cyrus, no Madonna, no Britney Spears can influence my brain.
No Lenny Kravitz, no Justin Biber, no Bruno Mars, no Brad Pitt, none of the great actors or rockstars can give me an idea for buying new products or for behaving.
The world has changed and celebrities belong to the past of marketing.
The new Mrs and Mr Anonymous are the testimonials to look at: life is too short and complicated not to follow yourself and your originality.
