Deal With The Devil? Blac Chyna Makes Pact With Kris Jenner For Reality Spinoff

Rob Kardashian and his pregnant fiancee, Blac Chyna, have scored their own spinoff— but the multi-million dollar deal came at a price, RadarOnline.com can exclusively reveal.

According to insiders, Rob's controlling momager, Kris Jenner, sat down with the Instagram model, 28, and told her she must give up her free will to in order to finally become reality TV famous.

"In exchange for the show, Kris made Chyna agree to remain married to Rob for at least three years," a family insider tells RadarOnline.com. "Also, they have to attend prenuptial counseling."

The savvy businesswoman, 60, is terrified of how another quickie divorce could affect the family brand, the source explains.

"Kris refuses to have another Kris Humphries nightmare," the insider adds, referring to daughter Kim Kardashian's trainwreck marriage to the NBA player, which ended after just 72 days in 2011 and turned the family into a public laughing stock.

"She wants Rob and Chyna to be the perfect husband and wife."

As RadarOnline.com first reported, Rob, 29, and her soon-to-be bride worked with Kris to secure a spinoff deal. According to E!, the "docuseries" will be called "Rob & Chyna."

"Kris wants to have the wedding and baby's birth included," a source told RadarOnline.com last month.

The series premieres later this year.
