Rob Kardashian and Blac Chyna's wedding special is said to earn the couple millions of dollars. This comes after they signed up for a docu-series on the model's pregnancy.

TMZ reported that Rob Kardashian and Blac Chyna's wedding special was not initially part of the docu-series. However, it seems as if the couple now wants the ceremony to be documented.

Apparently, Rob Kardashian and Blac Chyna are insisting on a seven-figure deal for their wedding special. The controversial couple allegedly wants to earn the same as Kim Kardashian-West when her wedding to Kris Humphries was televised. Moreover, Kris Jenner may be handling the couple's wedding plans.

According to IBT, Rob Kardashian and Blac Chyna's wedding date has not been revealed yet. There are speculations that the high-profile event may happen by the end of summer.

The model announced that she was pregnant with Rob's child last month. She has a child with Kylie Jenner's ex-boyfriend, Tyga.

"For a long time I felt like King was going to be an only child," she wrote on Instagram. "That he was my greatest blessing and we were gonna live happily ever after together just the 2 of us, I was no longer looking for love because I thought I had all that I needed."

"Here I am engaged to be married to one of the greatest men I know who loves King & I unconditionally AND having another bundle of joy! I just want to say never give up & ALWAYS have faith because fairytales DO come true."

It was previously reported that Rob Kardashian and Blac Chyna will have their own six-episode docu-series entitled "Rob & Chyna." The show is said to "follow the whirlwind romance" of the controversial couple.

Each episode of Rob Kardashian and Blac Chyna's TV show will give fans a glimpse of their engagement, the model's pregnancy and the birth of their baby. It is produced by Ryan Seacrest Productions and Bunim/Murray Productions.
