How do you get a 5 star celebrity on sims 3?

It's not easy to get celebrities friends. Look inside the Studio Town Insider and go to Who's Hot in Studio Town section. Whoever isn't in that list can be talk to easily but their last name must be Somebody. It's easy, just look who wears High Fashion Outfit and who isn't so popular. But you have to become a Insider or Name Dropper first.
