I don't believe there are any more nude images of her. And videos of her likely don't exist.
I don't know what was happening over at Simpcity, but she never had an only fans. There were only ever half a dozen nude images of her, which her ex boyfriend leaked out of spite. These same images were doing the rounds on various leak sites long before she was dead. If there was anything else, don't you think they'd be already out there?
Honestly, anyone saying otherwise is either trying to scam you or troll you.
