Kris Jenner may have confronted daughter Kylie's older boyfriend Tyga about "using" the teenager in an upcoming episode of the family's "Keeping Up With The Kardashians" reality show.

Radar Online reports the 59-year-old momager doesn't trust the 25-year-old rapper where her daughter is concerned, and it seems most other family members share her concerns.

"Everyone says they're worried that Tyga's using Kylie for her money," a source told Radar about the "Rack City" rapper, estimated to be worth about $4 million, compared to the family's more than $300 million fortune.

One recent episode that particularly raised red flags for the family centered on the $320,000 Ferrari the rapper gave his girlfriend for her 18th birthday.

"The family later discovered that the car was not only leased in Kylie's name, but she paid for half of the down payment!" a source said.

Reports are all the infighting may now even be taking a toll on the two lovebirds. Word is the two "are at each other's throats," fighting over everything from Kylie's career to her not having enough time for her boyfriend.

"If things keep going the way that they are between them, they will be done in no time," a source predicted.

That's a far cry from just a few weeks ago, when the two lovers were rumored to be planning to elope as soon as she turned 18 and quickly move out of Los Angeles to escape all the drama their daily existence has become. New York City and Europe were reported to be among the possible landing destinations on the couple's radar.

Since the two went public with their relationship, Kylie has regularly feuded with her boyfriend's ex Blac Chyna, with much of the dispute playing out on social media in a never-ending exchange of bitterly laced posts.
