Actually you either have to be a celeberity or have the same or better reputation as them. Also there is a lot trait that makes it harder for higher level celeberties to come to the lot but it don't stop them from coming, the 1 star to 3 star celeberties still come visit some, however, the 4 star and 5 star celeberties rarely show, I had to add it in the bar at strangervillie, because it killed the story with 2 global superstars and 2 or 3 4 star celeberties.
The lot trait is up and coming hotspot, if you put it on a non lounge lot the rate of high level celeberties will be low unless you create a event their that increases the rate of high celeberties. Lounges with that trait have a special community event called a celeberity meet and greet that allows fans to meet celeberties, this is not the same as the fan meet and greet your celerberty sim unlocks at fame level 3. One is the fan side of it, and the other is the celeberity side of it.
