Pre-fab growliness as mom-ager KRIS JENNER does whatever it takes to make an easy buck much to the chagrin of 2nd tier Kardashian spawn KOURTNEY and sperminatin' non-hubby SCOTT.

Kourtney is "furious" with her mother after getting the lowdown mom Jenner was hustling that exploited KK’s new daughter, Penelope, and NOW baby dada Scott Disick said enough is enough, RadarOnline.com reports.

"Kris immediately started trying to make money off the baby, literally from the moment she was conceived!” a source said.

"Kourtney was already getting annoyed during her pregnancy because her mom talked nonstop about branding girly things for the baby. And since the birth Kris has stepped it up with her money making ideas.

"Even Scott stepped in and told Kris to back off, he actually told her they needed time to enjoy their baby before they share her with the world.

"But Kris was relentless and started taking photos with the intent to sell them, and the whole family knew it.

"The last straw was when Kris wanted to take pictures of the baby during the birth, while she was coming out! Scott drew the line there, he said absolutely not!

"Both Kourtney and Scott have told Kris to step away, their baby is not some money making tool. They have a deal in place with a magazine to run the first photos of Penelope, but after that they want a little privacy for her."
