Blac Chyna & Rob Kardashian: We'll Make 7 Figures Off Our Wedding

Blac Chyna and Rob Kardashian have made a radical sea change ... they now want a TV special for their wedding, more than a million bucks, and they want the Kardashian girls there in force.
BC and Rob just signed on for a docu-series that will focus on her pregnancy, but the wedding is not part of the package.
Now we know why ... Chyna and Rob know that Kim scored millions when her ill-fated wedding to Kris Humphries was televised. They know they won't get Kim's money, but they feel more than worthy to get what Kris got, and they're insisting on 7 figures.
And one other development ... Chyna is on board to let Kris Jenner handle the wedding plans. No one can squeeze money out of events like Kris, so everyone wins.
