Why do i need to be assured to do something with the approval of celebrity?

Lately or for along time now, i need the help to buy games, electronics etc. I must google ''well layne stayle loves to play Metal Gear, or stone cold steve austin has an iphone" then i think i must have one.
it getting ridiculous, or if i see any celebrity i randomly saw on the internet doing or having something, i instantly want it.
is this normal?
