@DaniRose2143 that must be so irritating! I've found that a lot of things related to being a celeb in the game are very unpredictable. I have a celeb sim in one of my saves who's been trying to complete a milestone FOREVER to get 3 fans to ask for a selfie with her and it's never happened - not even once! And I hang around the gym all the time posing for pictures & getting the crowd riled up. Oh well. The paps showing up at your house must be rare enough, because I think it's only happened to me once ever, so if I were in your situation I might just bypass the natural order of things and get deco sims that I can pose around the place. I've had to do this a few times - sometimes it just gets tiring waiting for the game to behave.
I found these ones for you! https://www.patreon.com/posts/38245013
I hope this helps! It'd be a shame to have to leave out a part of the story you're proud of because of that
