One insider said earlier this week, “Everyone says that they’re worried that Tyga’s using Kylie for her money.”

Tyga, who has had his own rap career with hits like Rack City & Faded, is worth $4 million. And while that might be more than most, it’s chump change when compared to the Kardashian and Jenner family’s rumored $300 million net worth.

As for the momager, the source said “Kris doesn’t trust him.”

One of the first eyebrow raising moments came when it was revealed that Tyga was leasing the $320,000 Ferrari he gave Kylie for her 18th birthday. But the shocking news didn’t end there.

“The family later discovered that the car was not only leased in Kylie’s name, but she paid for half of the down payment!”

While Kylie and Tyga fought controversy of their romance considering she was 17 when she started dating the 25-year-old, it looks like their guards are coming down and now they “are at each other’s throats.

“If things keep going the way that they are between them, they will be done in no time.”

Meanwhile, Keeping Up With The Kardashians just returned for a four episode special on E!
