Kris and Caitlyn Jenner are reportedly worried their daughter Kylie spends too much money on her boyfriend

A source close to momager Kris, 61, and her 67-year-old former husband Caitlyn - who was known as Bruce Jenner before she underwent gender reassignment - told InTouch magazine: "Kylie spends] hundreds and thousands of dollars [on Tyga]. [Her parents] just want her to be smart with her money.

"Kris and Cait even involved Kylie's management team."

And the make-up mogul's parents aren't the only ones with concerns about the loved up couple, as Kylie previously revealed that the 'Rack City' hitmaker's friends didn't want them to date at first.

She said previously: "The first year we started hanging out, everyone around him told him not to be with me. I still get comments like, 'Don't be with him.'

"But we're not doing it for the public - we love each other. We need to be together at all times. We never get mad at each other, we just figure things out."

It isn't just Kylie who faces concerns over her funds either, as the '1 of 1' rapper recently appeared in court to discuss his own finances after a string of repossessions and troublesome bank account figures.

In September, it was reported that Tyga's mother was at risk of getting her Range Rover repossessed after the rapper failed to keep up the $1,000-a-month repayments on the $60,000 Evoque model.

Previously, Tyga's own Ferrari was seemingly repossessed, while he was also recently the subject of a $200,000 lawsuit filed by jeweller Jason of Beverly Hills due to an allegedly unpaid purchase of a watch and chain in 2013, and has had action taken against him by more than one landlord for unpaid rent.
