Could Rob Kardashian be going broke soon? That's what fans can't help but wonder as there's a new rumor swirling around that says the reclusive reality television star is spending millions of dollars on his future wife Blac Chyna and that unfortunately, there's no end in sight.

According to Naughty Gossip on Friday, one source exclusively told the site that Kardashian is doing whatever it takes to keep Chyna happens, even if that means he's bank account is dwindling away.

So far, he's spent $350,000 on an engagement ring for the model along with a luxurious purple Lamborghini. And apparently, the Kardashians are worried that Chyna might be using their brother for his money.

"Rob is spending everything he has to make her happy," the insider said. "It is like he is trying to buy her love. He has a lot of money but he doesn't have Kim money. He has not had a job in a long time and most of his cash comes from being on the family reality show."

The source added: "Kris still pays him even though he refuses to film, but he isn't earning the sort of money that he can spend millions each month on his new lady."

Even though Kardashian and Chyna have only been dating for a few weeks, they announced their engagement last month. So far, the couple has not set a date for their upcoming wedding. It is unknown whether or not Kardashian's sisters--which include Kim, Khloe and Kourtney Kardashian along with Kylie and Kendall Jenner --will be present for their ceremony.
