OHMYGOSSIP — Kourtney Kardashian and Scott Disick have come to blows over his spending. Sources say Scott has been “living like a king” at Kourtney’s expense — and she’s not happy.

“Scott has been spending like he’s Jay Z or something, while he completely cast Kourtney aside,” a source said.

“How can she not feel used?”

Scott has made $2 million from the family’s reality shows, but has blown the lot on amenities like fancy cars, extended stays at posh hotels, private jet rides and gold bling.

“All of the money he has is because of her,” said the source.

“Kourtney likes to look nice, but she isn’t someone that goes crazy on yachts and diamonds and elegant vacations like her sister Kim. She lives modestly and she has set aside a lot of money for for Mason and Penelope.

“Kourtney could live off the rest of her life for the money she’s made.

“He puts himself first and pretty much every situation and just makes the wrong decisions – unfortunately, Kourtney ends up getting hurt.”
