Blac Chyna was paid $15 000 (R197 517) for a club appearance over the weekend.
The 29-year-old reality TV star - who recently splashed out $334 000 (R4 398 000) on a 2017 Ferrari 488 Spider - hosted a party at Project Club Los Angeles but was paid the lump sum in cash before she began working, TMZ reports.
Chyna and her new boyfriend Mechie spent one hour at the club before leaving.
Meanwhile, Chyna - who has daughter Dream Renée, eight months, with former fiancé Rob Kardashian and son King Cairo, four, from her previous romance with Tyga - recently insisted she is financially independent.
She said: "I make my own money. I've been making my own money for a very, very long time. My first job was at McDonald's when I was 15.
"Years later, right after I had King, I wanted to do something that expressed myself, so I started Lashed Cosmetics. The lipsticks, the full skincare line, the beauty bar and 88Fin clothing trickled down from that. Nobody supports me at all. If anything, I've gotten other people more money ... I'll leave it at that."
She also insisted that she gave Rob back several gifts after they split up.
She said: "I gave back Rob's jewels because I feel as though I can't be bought. I'm not going to let [him] hang something over my head anymore. I also read that he said that he took the cars back. No, he did not. Those cars were leased, and I was going to have to give them back anyway.
"But the day he posted all that stuff, I had two of my assistants drive the cars over to his house along with the jewels, along with my engagement ring. You know what? I didn't even ask Robert for anything back. I'd actually bought him a Range Rover."
