@superkyle221 It's one thing to help a celebrity up the ladder of fame a bit, it doesn't cost much. Katy Perry was not so much of a huge star all over the world that she is now when she ok'd it.
I doubt if EA could afford another Katy Perry type pack these days, much less Meryl who likes to keep her herself private and she wouldn't like this kind of thing. She would have to be approached for her permission through her agents. She doesn't need it.
The cost of a top of the list celebrity would probably bankrupt Maxis' Sims 4 budget.
Leonardo di Caprio still gets about $20 million per film, Jennifer Lawrence $10 etc. Money best spent on more Maxis employees for better game packs.
